I noticed that it happens more frequently to all vids now. Seriously, last month, videos lasted at least a month, and that gave them partial immunity on the site. Now, things are being taken down within the first 3 days. Any recent uploads are less safe than anything from last month and beyond that.
Sadly, I think I know why, and it's a tragic one. It's partly our fault. We keep trying to tell those damn users to grow up and accept something that they don't like on the site, we spread so many subliminal messages, and what does it do?
It pisses them off and practically forces them to take their anger out on us and make us suffer more by removing everything that user who tried to spread the message uploads no matter how good it is.
