DDos attacks against BitTorrent

This past Wednesday, key BitTorrent networks, LokiTorrent and Suprnova, were brought down by a distributed denial-of-service (DDoS) attack. Those who use the file sharing networks to find peers with movies, music and other digital media were unable to for about 10-hours. The attackers are unknown. I'll speculate though. DDoS attacks have been the tool of nefarious individuals that wish to claim bragging rights or make a political statement. I can't believe that individuals of that ilk would want to bring down BitTorrent. Unlikely -- the opposite is more likely -- they would be champions of the peer-to-peer networks. I also highly doubt that the usual law enforcement agencies would be investigating this one. Why help out a group that champions the illegal sharing of files on the internet? To take a SWAG at this, I think it could have been the RIAA or the MPAA -- or some other software giant. Ironically however, this type of attack doesn't bring down the BitTorrent network, because it's peer-to-peer. All it does is hamper users from getting to trackers that contain information of the peers with files.
