We all know how bsdforums.org was flooded with spam and nothing serious was done to fight it...I saw you use reCaptcha to prevent spam. This is not enough. It clearly won't stop spammers. I suggest using a challenge/response feature to further stop spammers during registration. The question asked should be taken from a pool of questions and answers, and should be related to FreeBSD so that regular spammers can't reply properly and give up. For instance if you ask something like "What starts with the letter K, ends with the letter L and can be compiled under FreeBSD?" I doubt a regular spammer can reply properly. If we wait and see, we're going to run into much frustration fighting the spammer armada :\
