Running an exit node when you're doing anything illegal is retarded. There was an exit node operator who got raided and one of the people on OVDB knew him. That's all the details I'll give about that. Not a good situation. Oh, and this guy (who outed himself, so I'm not giving anything away) had a small amount of MJ and hash, but still not a good thing when you're running an exit: http://raided4tor.cryto.net
