My website has been up and running since early February, and to date, 9 individuals have manually registered and attempted to post inappropriate content to our car enthusiast website.
I wonder how they find the website to attempt this, but thanks to VBulletin.org, the spam filters I installed have sent all inappropriate material to the moderation queue for review and deletion.
I started a forum and thread on my website to post their screen names and IP addresses:
