Hello friends, hope you're enjoying the video. Just wanted to address a few questions that I've been seeing a lot in the comments. #1. I'm not a hacker, this isn't a hacking video, and I didn't hack anything. I did not do anything that a normal person (victim or not) couldn't have done. No hacks, no exploits, no vulnerabilities, no break-ins. Every action I took was publicly available to me and everyone else that went to that scam site. #2. For those concerned that the scammer is using a stolen card to pay the bill, don't worry too much about that. Consumers have zero liability for fraudulent use of their card. Banks will issue charge backs to recoup their money and the burden will be on the processor and thus on the scammer. Additionally, getting an account with a payment gateway cannot be done anonymously and gateways use a bank account to forward the proceeds to and withdraw the charges, if necessary. So either the scammer gave their real information because they are operating in a country that is lax on the rules and is legally on the hook for the charges, or the processor is in on the scam as well. Regardless of which case it is, nothing bad is coming to any victims. #3. My efforts are not pointless. At the time of this writing, this site as well as every scam site in the long list of scam messages on my phone is offline now. Although I seriously doubt it was what I did that caused that, I can only hope it helped a little.

the most impressive part of this video was seeing how he added single quotes and colons to that whole dictionary at once

Literally laughed my ass off when he said "Just the infinite loop isn't fast enough, let's have 50 threads running this simultaneously"

I work in fraud and you've fulfilled my most common work daydream. I've never laughed so hard and maniacally before, thank you

Been learning python for 3 days now. I’m glad that I was able to understand a quarter of what he was doing, or at least understand parts of the code. Still got a lot to learn 👍

-Me, who has 0 programming skills, 0 Python Knowledge: "Yeah good idea,do that"

I just learned threading in Python.

After watching i couldn't help shake the feeling that the script that the form was submitting to could have just been a phoney response made by the scammer to simulate a decline, so that the victim thinks theres something wrong with the card, possibly making the victim either use another card or just causing the victim to reach a "dead end" so they leave the site thinking their card wouldn't work in time, when in fact the scammer has already stored their CC credentials.

I've got zero experience with python, but lots with other languages. I was amazed at how simple and easy to understand the code and what you were doing. Can't wait to dig into this stuff more!!!

Alt Title: Making the scammer pay for an actual PS5 in decline fees.

Imagine creating a scamming website only to lose $3 every second.

A few things I'd do differently: You can right-click on the request and copy it as a ready request that can be sent directly in a few different formats - that would save time getting it right. Then, I would send asynchronous requests, you don't have to wait for the response this way, so you can really pound in those requests. I'd also aim to use a proxy just in case. Javascript has a better support for asynchronous requests, but it can be done in Python as well. These are just some technicalities in the end though. Your approach has done the deed just as well :)

I could see my own light bulb go off when I was listening to you process the pain you were about to cause. Very impressed and definitely had an evil grin of satisfaction watching.

You should've made a "loss counter" which would add 0.05 for every successful response and print that data on screen to display how much he'll be charged.

in case anyone was wondering if each REFID decline cost $0.05. The actual amount his final script charged the scammer is $2228.3 USD

If you ever see a scam and wonder "Wow, who would be stupid enough to click on this??" this right here is *exactly* why scams look the way they do. They don't *want* people who know better to get this far, because they might just know how to break their system

Love this, this made me feel proud hearing about how you punished them for being scammers, dubbed and liked. Definitely improved my night

Me: "cool, an infinite loop left overnight to punish the scammer" Engineer Man: "It's not going fast enough. Let's use threads" Me: "Time to hit subscribe"

This should be a compulsory exercise for CS undergrad students.

You make me want to learn coding. I took a class and was so fascinated, but there’s so many details that takes me awhile to wrap my head around. The way you show it and talk about it makes it seem a lot easier than it has in my head over the years.

This video generally got me way more interested in how coding works and how threads work and all that stuff just because it really engaging Thank you so much

You should just let it run for 10 hours and stream it. When I'm feeling down, I can come to the channel and just smile for a while. 😊

Dude didn’t stop at the infinite loop; he added 50 threads a loop. That’s some serious punishment.

Crunched the math, if each decline was 5 cents, you just costed that guy 2,228.30

this was the video that motivated me to become more invested in programming. thank you so much for your content.

Can't even imagine the face on the scammers realizing they just got scammed 😂

You should make a series: "learn python by beating scammers"!

I've been coming back to this video over the years haha, and I'm still impressed with some of the things you do here

Even though I had ABSOLUTELY NO IDEA what you were doing in Python, I found this hilarious. If it really is about 5c per declined attempt to the scammer, I would let the script run until the scammer has to shut his PC down to stop it, then fire it up again and run it some more. YES, I hate scammers, they are even below the level of "scum of the earth". I wouldn't piss on one if they were on fire.

Tinder Date: Sends more than 5 messages in a minute. Engineer Man: Spam the inbox using python to assert dominance.

First time seeing your video and I must say this video just gave me life!! Definitely earned a new subscriber! Thanks!!!

Just started learning to code this year 2024! This kind if content is absolutely amazing and motivational. Your calm deamor while destroying this scammer is awesome. Even though I didn't understand most of this, it's all good. Eventually, I'll get there.

absolute legend

I would love to be a fly on the wall when the scammer watches this video.

Holy shit dude, you're a legend. I don't know how to program but you look like a god damn wizard. Love this kind of content. Hopefully you're right about card decline fees!

Excellent videos, to be honest my head was spinning with my small computer skills, well done , keep up the good work.

Ok but is anyone gonna talk about that super useful method of editing multiple lines at once 🤯

As a former CS student who has now switched majors, I'm just shocked that you can type a comma on multiple lines at the same time...

it’s amazing how simple yet effective this line of code is, beautiful work good sir

Awesome and informative video AND scammers get punished - what's not to like? The perfect video basically! Thanks for doing this!

That’s 10,000$+ in damage with some lines of code...

I am just learning Python and the big thing from this video was the way you formatted all that data simultaneously to make a Dictionary. Got out the manual and figured out how to do that myself. That was the big takeaway for me. Thanks.

I really enjoy watching videos like this and it makes me want to stop scammers like this guy

This is the coolest way I've seen it done...brilliant

As a computer science student with experience in multiple programming languages, I am shocked with how such simple code can lead to hundreds of thousands of dollars for this scammer. You really let this scammer off the hook by stopping it that early, had you let the code run overnight he'd of been millions in debt.

I love how the "amazon" offers you a free ps5 but doesn't want to pay 1$ worth of fees

Oh my god watching you code was beautiful lol I love it when scammers get punished!

seeing how effortlessly this man added the quotes and commas and all of that to data

"I think we've pretty much sent them enough..." Oh, no, I don't think we have. Turn it back on and let it run for days, please.

The fact he is so calm is just amazing

Probably one of the coolest videos I've ever seen on youtube, thanks.

"We could do an infinite loop, but the problem is this 2 second delay, so it's not running fast enough" Dude, you are AWESOME!

There should be some sort of award/reward for guys like you who are fighting for us against the scammers!

I understand nothing of what you do but I totally get the spirit of why. You're brilliant. You shouldn't have stopped it!

genius mate love it ..my mind boggles when i see you guys i have sent maybe 30 emails in my life am 55 ,terrified of computers really just dont get them ,never been shown i guess .too late now but top marks and cudos to you

I absolutely loved the video and definitely wanna see more of this. I have 1 question, though. Doesnt web site or credit card company have some sort of protection against this? I mean, its kinda similar to DDOS attack, so wouldnt there be something recognizing so many requests as a form of bot attack and prevent further requests?

Thank God someone who knows programming and how to stick it back to the scammers is giving them what they deserve! Bless you! Thank you from older people that only dream of doing this.

Engineer man to the rescue. Not only does he thwart a bad guy but he teaches us all a little programming along the way.

This man is doing God's work. Thank you for the chuckle. Signing up for Python classes!

Alternative title: motivation to start learning python.

I loved it... I am a retired programmer and amazed at your knowledge and skill - Great Job... Love your punishment... please create some more to get rid of the scammers

It's always satisfying to see people using their skills for good, especially when it comes to combating fraud and scams. As someone who's interested in both technology and finance, I'm always looking for ways to improve security and protect people's assets

so simple yet so devious, this was just delightful to watch

Now just IMAGINE the number of people from the audience running the same program after seeing this.

Engineer Man (3:25): "It's highly probable that every time I click that 'Order Now' button, it's charging him about 5 cents." Engineer Man (6:48): "The transaction IDs are like 20,000 higher than they were before." Me: *Looks up $0.05 x 20,000* Scammer: *Loses $1,000 in less than 30 seconds*

3:28 I busted out laughing because I knew where you were going with this 😂 you had that smirk on your face too.

Oh my goodness you're the best!!!!!! Alot of why I wanted to learn to code is to get scammers and to mess with them. My mom is super susceptible to them. Not all heros wear capes!!

Plot twist; the scammers are forwarding requests to a real company’s payment gateway, not using their own. I’ve seen this often. Validate CC cards against a legit companies’s payment process, then take the successes and use (or sell) those at a later date for fraud.

You can speed this up significantly by ignoring the response, just send the request with a very small timeout and ignore the timeout error.

I absolutely LOVE these types of videos! too bad there aren't much of these

I finally came across this video again even though I couldn't find it for 2 years. just in 2021 this video impressed me to learn python, it's still the best thing I've learned

As a python developer myself, this is actually simple and clever method. Great job!

Dude, you rock! If I were you, I would've let that program run for the weekend. You should set up a group of fellow programmers and just screw with scammers. You Are A LEGEND.

Awesome job man, keep up the good work

I really enjoyed this video:) so cool you made them pay for scamming you, well done sir!

Me at the start: I don't understand how it will punish... Me at the end: I don't understand how it works, but i know that it's incredible...

Bro, you should literally get a reward for punishing that scammer. Brilliant

This is gold man ill always check scams for stuff like this from now on

@Engineer Man Great job. I wish I knew how to do what you did. I’m so sick of seeing scam emails. I get at least 4 scam emails every day.

You should talk to Mark Rober, Scammer Payback, and I forget who to help in their anti-scam alliance.

I’ve always loved watching people code. I am really overwhelmed looking at it and it seems so daunting but man is it satisfying watching someone do it

LOLOL that was great! I literally just started learning python last week and I'm excited that I understood a bit about what was going on! That was a great way to use it👍

why did i never see this channel before THIS IS GENIUS!!

Would love to know how much the scammers were slugged by the credit card declines. If it’s Five cents per decline then at let’s say 50 declines per second, that’s $2.50 per second or $150 per minute or $9,000 per hour. Nice.

I've never EVER thought programming was so easy. This is the first time I've found coding so understandable. Instant sub

Love this! Wish you'd let it run for longer though. Keep it up!

Excellent! You’re so much nicer than I would’ve been! Makes you want to hunt them and punish ALL of them!

Imagine that scanner watching this video and crying for getting robbed by an infinite loop.

WHY did you stop? Someone like that deserves a dedicated cloud instance to do this on 😉

I learned some valuable lessons from this video! Thank you!

Thanks for showing your programming process. I didn't know you could track requests using Chrome; I'm definitely going to use this in some of my programs.

scammer: just casually tries to scam people this guy: so you have chosen death

This was beautiful. I learned more on requests and threading. Thank you sir!

Glad to see scammers being punished and it actually teaches me some new stuff to use in python as well so thanks for that

Pro tip: you can copy the request as curl from the dev console. You can later convert the curl request to your programming language with different tools (I use postman)

i understood 5 words in this video, including 'if' 'and' and 'yes' glad there are people out there like you doing good with your skills!

That was straight savage. Hit 'em where it hurts. I am glad to see someone with the abilities you have take on criminals like this. Keep doing what you do.

Learned more about threading in this video than anywhere else. thanks :D

That was the best, most interesting video I've watched in a long, long, time! Make them pay!

This is phenomenal on so many levels but the threading part has helped me solve an issue with another script I've been making. Keep up the amazing work!
