I've even seen it happening on pure music videos. It was the pinnacle of how brainlessly this feature was implemented.
YouTube auto-translates these videos, with the end result being a random toss between the original uncensored speech, the modified speech with some sex term added in there (and unbleeped!), and random nonsense - all of it read in a robotic monotone voice.
The end result is completely unwatchable, except perhaps as a dadaist experiment. I can't understand how someone hasn't noticed it yet.
