Hey people.
Well i don't think it's the right forum to post questions like this, but i'm just in need of quick advice.
I've set up a forum recently, after it was indexed by Google the entire forum got spammed. This lucky, for some, day turned to nightmare for me. I use vbulletin with all necessary fixes, but it's turns out that everything i've done is useless. If there's anyone is familiar with vbulletin, please suggest some ways to stop this.
Almost forgot, these spammers left these links:


Any idea on what it is? Why would someone even bother spamming this stupid stuff? I mean spammers work for 24/7, but what they try to accomplish with this nonsense spam?
