Forum Bot Attack Help!

[محروم.كوم]

I have been attacked by porn and other garbage today, its never been worse. vB 4 has something they found.

Never the less, I was forced to put registration in moderation mode. As soon as I did this over 175 emails with this ip pointing to various urls to the site have come to me so far with this message. I'm hoping someone here can help me identify whats happening.
