We’re not getting any kind of joy out of seeing your video, believe me.  What it does is give us the chance to report not only the video given but any others we find on that account.  YouTube has a “3 strikes and you’re out” policy, so if we can report more than one video at a time, we can get the account shut down much quicker.  We also know the best way to get a video removed as fast as possible.  Most people we’ve spoken to will report their video but not any others.  We report every one we see.  We’ve managed to report hundreds of videos and get dozens of accounts closed that way.   Getting the account removed also gets rid of any hidden or private videos, which can take days to have deleted otherwise.  Sometimes they’re removed within 5 minutes of reporting them, which is always a good result.
