This is likely because they aren't stupid enough to take on a massive corporation (so many vids from so many sources; it'd take quite a while to get them all), but we're a small operation that's far easier to harass.
Sort of like how the Chinese/Russians practiced hacking & spamming this site before attacking the government. We were just practice for their hackers. Ever notice how they don't bother us anymore? They've moved on to bigger things now that their hackers used us to 'get good'.

Dave AuJus:
Well that just sucks. I really liked his stand-up comedy.
FYI - His lawyers haven't taken down any of the videos on YouTube yet.
