Prevent Threads with Certain Titles

[givememyleg]

Hello,

I have vb4.2.2 installed and after some updates, most of our spam is under control. We require captcha and do not allow urls for users with under 3 posts and that prevents a lot of spam bots.

However, the bots are getting around this by pasting the url in the thread title like this:

Title: http://theirdumbspamsite.com/some-page/
Post: garbage spam

Is there anyway to block new threads, or queue them for moderation, if they contain "http://" or something similar in the thread title? No normal users use "http://" in the thread titles, 100% of the time it's spam.

Thanks
