I have added a forum to the blog some time ago, but I had to delete all the users and threads as it was spammed like hell.

Now I have added captcha and a box where people have to type YES to confirm they are humans. However, I still get 20 users per day who are spammers. What else should I add to avoid these guys? I am worried that when I launch the forum for everybody I wuld have users that I will not know are spam and others that are real members interested in the forum.
