Forums
Over the last year I’ve been in significant battles with spam on my forums, so much so that I’ve purged them three times this year. I always make sure I have the latest version of SMF installed, I have the email confirmation turned on and the Captcha feature turned on.
Unfortunately people were still posting a ton of crap on there and so I have now made it so I have to approve members, which is basically my way of NOT approving anyone who signs up. I’ll more than likely remove the forums completely if I can’t find a better fix in the near future, so for now just email me or post a comment on the blog if you have a question.
