As you know, we've been getting hit pretty hard by spambots lately. I just set up a system that should prevent them from registering - reCaptcha won't work anymore because it's been cracked.

However, this system wouldn't prevent spambots that are already registered from posting so it was necessary to prune users. Which is why we are missing over 2,000 members now - I deleted everybody with 0 posts except banned users. I did send out an e-mail to all of the users in these groups to explain to legitimate users what was going on, and to encourage them to re-register.

If the problem seems to be solved then I will turn off post moderation after the weekend. It is currently enabled for New Members and requires their posts to be approved before they are submitted, but this new system should negate that necessity.
