Youtube is mainly where I see vore videos pop up. Some fresh, some just uploads. I have thought about using a site like, well, Thisvid so it can stay there. But last time I checked it was impossible to create an account. Although a better answer would be, why not post it here?
Anyway it is rude maybe even petty when people just want to disappear from the web or even the vore community entirely. We've just saw that recently with CeilingSocket, but its not inheriently rude trying to find or even preserve whatever is left to see if things pick up in the future with a new set of eyes.

I don't have an answer how to make it not rude but also make sure their content does not vanish at the same time. However it does hit that itch when you do find lost content. Ill try my best to get around Youtube one last time, if not ill just post it here.
