On a few videos by FunnyFuse as well as one by Cinemassacre bob has triumphed. We may expect to see the full return of the old comment system in the near future!
Google integrated their crappy social network into the youtube comment system which broke a whole load of stuff and generally made youtube shit. But people hated it and the mascot for the "Resistance" was an ASCII art stick figure called bob who built an ASCII army of tanks and planes and helicopters to take over Google+ and well.....
I haven't been prevented from watching any videos.
I did notice that recently the quality of comments seemed to be improving, at the very least there were far fewer rubbish comments (not that I read them, but the top few are always visible, so you tend to notice the spam and trolls). Is that what you're on about?
