Alot of problems with spam
 

My site is having alot of problems with spammers registering and posting VERY pornographic pictures. I'm banning about 4 or 5 a day. How can i stop this? Is there a way i can set it to where a new user can't post pictures until they've had so many posts?

And if so, can someone tell me how to do it? I'd really appreciate it.

Thanks in advance

1. Create a "New Users" usergroup and take away PM and thread starting rights.
2. Create a promotion from "New Users" to "Registered Users" after 5 posts.
3. The "Registered Users" usergroup should still not be able to send PMs, but can now create threads.
4. Use CAPTCHA and e-mail verification.

Make sure your using the latest version of vbulletin

In the left column of the admin control panel - vbulletin options drop down - human verification options - either use image verification, question and answer or setup ReCaptcha.

If you are using the standard captcha phrase, the spam bots broke that a long time ago.

I think there is a modification where you can use 2 or 3 of the human verification options at the same time.
