Our 3.6.8 forum are in big trouble!!! TOO MANY SPAMMERS
 

within 9 days, there are totally more than 1400+ registration, and many threads of "Hello from xxxx xxxx" with the same content.

My 3.6.8 vbulletin forum suffers a lot of attacks.

How can we stop those damn spammers? I've set regsitration email comfirmation, post every 60 seconds, registration image verification, ect. All these settings can't stop spammers.

I am getting crazy now!!!!

Any suggestion?
