Trackers in general aren't illegal. You can host a tracker with legal content. You can't host a tracker that serves up zero say scene releases. Just like a router in a sever farm that serves cp is part of an illegal operation. There is a gray area where you'd host a tracker that serves legal content but some copyrighted material gets through. The DMCA safe harbor should take of that. But most of these torrent frackers are so obviously designed to host pirated stuff that dmca won't cover them.
