So, it turns out What.cd might be shutting down temporarily (hopefully not permanently) soon. The CRIA, probably more confident after kicking Demonoid out of Canada, is demanding What.cd's host to stop hosting them and hand over the personal details of the administrator(s), presumably so they can go after them. They also want site logs, but it's unlikely that the Canadian authorities will want anything to do with most of the users.
Remember though, just cause they demand it doesn't mean they get it. In Europe, torrent trackers are fighting all sorts of lawsuits, and I think at least one of them has won.
