BayTSP is a agressively spamming corporation who claims to be "Fighting Online Piracy in 2005".
 The problem with their story...
...is that they are not "fighting online piracy". They are fighting on-line freedom of speech and they are fighting anyone using BitTorrent.
BitTorrent is a legal file-transfer protocol used by Internet television channels such as The TorrentChannel to distribute large video files. Alternative media channels are viewed as a threat by the large media corporations who hire BayTSP, which is why BayTSP are agressively attacking anyone using BitTorrent for any purpose.
 BayTSP even spams people who are not using BitTorrent
It is, as pointed out in numerous blogs and publications, very simple to report any IP/Port number to any BitTorrent tracker.
Thus; it is interesting that BayISP only check trackers for IPs listed there and spam the ISPs these IPs belong to without even checking if the actual IPs in question are running a BitTorrent client.
This means that your ISP can get spam with a "DMCA notice" on your behalf from BayTSP even if you have never used - or heard of - BitTorrent.
 The legal status
It is unclear if BayISP's behaviour is criminal in the US. It is clear that BayISP's spamming is criminal in many EU countries.
