I'm a big fan of exploring but I think there should be limits. These are very fragile priceless ruins and walking all over them is destroying them.

We don't go inside anymore. Watch the trek planner and other bloggers, they show extreme respect.Please get an extending selfie stick. ❤

First, while I understand the preservation aspect, these are still "ruins". As long as these explorers do not destroy the integrity of the walls, foundations, etc I have no issue with their capturing on camera. Either they will document or science will document. I don't see any group/org out there trying to document the same, or to show the life that was there, so I appreciate the efforts of these guys to illuminate what is being neglected. However, these ruins will continue to disintegrate over time, and with exposure to the elements, so at least "someone" is trying to document it.
