Why doesn't someone here start up a tracker site.
Ask yourself if you'd be willing to do the same, given the current legal climate surrounding trackers providing copyrighted material. Legal issues may or may not be the reason for the impending shutdown*, but in the meanwhile, starting up a tracker when the constant threat of legal action hangs over your head is a senseless thing to do. This has nothing to do with anyone's personal stance on filesharing/p2p downloading/etc. It's just a fact, given the current laws.
* I don't really care to know what the reasons are anyway, since I'm not that nosy, but if I had to guess, I'd say that's what it has to do with. If the site owner/Admins wanted us to know what's going on, they'd have told us by now.
