As some of you may or may not be aware, the security verification that kept spam accounts from being created was cracked a little while back. Since that time, we've been inundated with false memberships. Xehn has taken up the job of filtering these out, but it's a job akin to taking out a hydra.
Starting immediately, if you are a new member and have not posted something within 1 week (We have a New Members introduction thread that's perfect for this), we reserve the right to assume it's a Spam Account and delete it. Unfortunately, we will likely delete some legitimate accounts because of this, but until we get a new verification process in place, this is the best we can do.
1/25/2011 Update: Well, it worked for a while, but we've been hit with a new wave of spambots. Shadowdragon has implemented some new security features that should help out. Among them is a moderation queue for new accounts. Until your first post has gone through the mods, your postings will not be viewable by the forum population at large. Unfortunately, this is going to make things a bit more difficult for new users, and we apologise for the inconvenience.
