iframe attack
One of the webmaster is purposely attacking one of our forum using iframe attack. He basically runs a popular forum and he put the following iframe code on his main page. When visitors on his site wont see our site because the width and height is "zero". He create something like 20 iframes on his main page which links to our forum. On a busy night, it will crash our server. Is there any way to block it?
