kripkenstein writes "The big media companies immediately assume you are guilty by your mere presence on a BitTorrent swarm, an investigation by a university security worker reveals. Turns out companies like BayTSP (which the media companies employ) will send shutdown notices to ISPs without any evidence of copyright infringment; all they feel they need is an indication that you are reported by the tracker to be in the swarm." From the post: "For my investigation, I wrote a very simple BitTorrent client. My client sent a request to the tracker, and generally acted like a normal Bittorrent client up to sharing files. The client refused to accept downloads of, or upload copyrighted content. It obeyed the law... With just this, completely legal, BitTorrent client, I was able to get notices from BayTSP. To put this in to perspective, if BayTSP were trying to bust me for doing drugs, it'd be like getting arrested because I was hanging out with some dealers, but they never saw me using, buying, or selling any drugs."
