Yeah, that was a bad move on his part. But why should Badspot care? If I remember correctly it was Lub who carried out the attack, Ephialtes just pointed out the security hole in Kalphiter's management system or whatever the hell it was.
Because having a forum moderator that attacks other members' hosting services just isn't acceptable. Apparently, because it's owned by Kalphiter then it's okay. If Kalphiter had done the same thing with RTB then the outcome would have been a lot different (forum ban, key deactivation etc)
Also, according to the server logs Kalphiter posted, Ephi participated in the attacks.
