Notice: You have been identified as a bot, so no internal UID will be assigned to you. If you are a real person messing with your useragent, you should change it back to something normal.
What it does, it copies videos and puts an animated fuckface in the corner making faces. You can autocopy the entire youtube and reupload it with that. I especially like the "reacts-to-reacts" videos of the fuckface reacting to some other asshole reacting to some other thing.
