VBulletin spam registration Captcha

I am an administrator of several forums. From phpbb to vbulletin.  There has always been a problem with spammers registering to our forums. Then one day I see the light. I noticed that despite our countermeasures in place, namely captcha, they are able to register with ease.  And looking at the logs, it seemed obvious that they are able to automate and decipher the Captcha.  Don’t ask me how but these bots can.  So I tried changing the default Captcha settings and boy was there a drastic reduction in spam registration. But what really did it is when I use Question & Answer Verification instead of Captcha. I believe only available in VB4 onwards.

Spam registration is now a thing of the past and it feels great!
