We got hit with some child porn spam today. What more can be said than this sort of thing is violently disturbing. I have now added two more spam fighting tools in hopes this never happens again.
1. Akismet service. This is a subscription service that scans the posts of new members for a variety of spam/porn keywords and locks the accounts down. It also scans new material against some known spam that already exists.
2. No links in posts allowed until a user makes 5 posts. Often spammers or bots signup and immediately post spam or porn links.
With these new tools combined with our other tools we should be able to reduce most spam.
