When I browse to this page I get the following in big fat letters
Our requirements are that you must post at least two messages, to allow the moderators to review your registration, before you will be allowed access to the full range of forum areas.
Considering all the spam lately I'm not sure the above "rule" is actually implemented properly? Or are you saying that all these spammers lately have registered a long time ago and only just now returned to post?

Anyway, it's quite common to have your first post(s) moderated and I think it's an acceptable compromise. Heck, at one point not too long ago, despite having made thousands of posts, I had to have my posts approved for some reason (I don't think I had been naughty) :-) In my mind it shouldn't scare off genuine users interested in the actual topic of the forum.
