What do you use to stop spam on your forum?

[J98680Bxxxxx]

In addition to the Human Verification, reCAPTCHA etc... activated, I have been using the following quite effectively:

1. Check Proxy RBL on New User Registration
2. Is Bot: Registration Time Check
3. vbStopForumSpam
4. Spam List: Block 261022 Registration Email Domains

Those spammers (*) who succeed in passing through these lines of defense will manually (through Moderation using "Check4SPAM - Advanced SPAM Search & Destroy!") end up in a "Miserable Usergroup" fortress.

(*) Here are some of those spammers who have succeeded in passing through and manually ended in the "Miserable Usergroup". They do not disturb my forum any more.
