Increase in spam?

Is it just me or has there been an increase in spam lately? Quite a few other forums have a feature whereby the first couple of posts by a new member has first to be checked by a mod before appearing on the board, does this one have it?

I know it won't stop the more determined spammer but should help alleviate the problem as most spammers will want a quick "in and out" and having to come back and post a second or third post before their crap is displayed on the board should prove to be a deterrent.

Just my 2c worth.
