I don't know of any IRC network that would go against their privacy policies to 'feed' the record industry associations around the world. Even a court wouldn't be able to force the handover of information because these associations are just citizens like you and me, composed of self-appointed representatives not government/law enforcement bodies.

It's not half obvious that is a bot advertises !Michael Jackson - Thriller.MP3 that the song would actually be that song and not an uncopyrighted song disguised with that name.
