It's seems the swisen.com has been attacked by spam registration, you can check this remote user on his site:http://swisen.com/onan95
and you can see the "real user" is a spam url for advertise:http://www.eblackjack.com/double-attack-blackjack.html
lovegx999 and I have talked about this ( we talked on this site in some chinese :),
and I think maybe these bad guys used the remote subscribe function to do this attack.
so, how can I turn off the remote subscribe function? or how can I make it "spam free" safely?
