Just like I predicted on several occasions, YouTube's over-the-top, self-defensive copyright policy has been purposefully abused on a large scale in order to trick YouTube into haphazardly removing videos it had no business being worried about. A currently unknown person registered with the username iLCreation, hopped on YouTube and claimed copyright to each and every Justin Beiber music video. What do you think YouTube did? Took the copyright notifications of an exceedingly famous artist's every video 100% seriously and shut down Beiber's entire Vevo channel without asking for any sort of proof of the claims. As if that weren't enough, a similar attack affected Rihanna, Lady Gaga and Bruno Mars.
It makes sense that YouTube enacts their policy this way in order to protect themselves, but this really lays bare how ridiculously extreme that policy is. If the process hadn't been automated and they had given even one second's thought to the situation, you'd think they might come to the conclusion that "Hey, about 5 pop superstars are participating in copyright infringement against one dude and he just noticed and thought to do something about it now, all at once? Hey, wait a minute...." Except that YouTube's all-complaints-are-true, automated copyright policy kept them from arriving at that second sentence.
