Kurupt.ru was neither compromised nor voluntariliy shutdown. An issue with one of the hosts caused the site to go offline.

About ICQ, 641487360 was compromised and recovered in January. ICQ allows anyone to reset your password based on your inactivity, that's one more reason for dropping this crap. It's regrettable that some people have been ripped off by the impostor but kurupt.ru bears no responsability for it. There were enough topics about ICQ.
