torrentreactor.net is up
dont know about the mpaa, but the riaa has backed down everytime theyve been challenged
attacking the torrent sites if challenged will turn out to be illegal, most back off and shut down their sites, mostly its an issue of $$ to fight back, the mpaa knows this and are using it to their advantage, enough sites fight back though and the mpaa will have to find another way, they have NO CASE legally
as far as p2p networks and people seeing your ip, so what, unless they do some packet sniffing theyve got zero evidence, and in order to do that the best way is to get the ISP's to do it, not likely, and even if they did, data encryption fixes that, and if your that paranoid, bounce your stream thru a proxy server, lots of free ones to choose from
