Implenting Captcha For Creating Discussions
I am having a large problem, now that my site has grown, with spam.
Regardless of how many IP's and e-mails I block, they keep re-appearing. I've implementing numerous ineffective anti-spam plugins as well as requiring e-mail verification.
My only other idea is to force them to fill out a reCAPTCHA to make a post. However, the thing is: They have to fill out a captcha to register in the first place. So however they bypassed it before, they can do it again.
Maybe I should be asking: Is there a way to maybe ask a special question on registration to verify they are human or change it to a more effective captcha?
