People can kill for some easy money, thousands do this even when there are serious consequences, even death penalty in some cases, just watch the news of a 3rd world country. What can you expect from people in general, when asking them about being honorable and respecting the wishes of someone that shares zoo porn? specially if its published in a public forum, server etc that gives anonymity and is to remain only in there. People who shares original content needs to understand that eventually it will get published and shared everywhere, you are sharing with the world, literally. Watermark if you want, censor as good as you can, and think in things that can make easy to identify you and that's it, no need to get overly affected for something inevitable that people should be perfectly aware of.
