MPGH Spam Reduction Idea

I think that MPGH should have an AJAX based system that tells you if a thread with a similar question already exists. Basically, when you type in a topic title, lets say I typed in "I NEED A HACK", it does an automatic internal search/filter, and if it is all too similar, don't allow the topic post.

EDIT: Another idea, instead of not allowing you to post, just tell them that there are similar threads and link them to it.

Sounds like a good idea. But MPGH.net would be down for a while doing maintance then
So good and bad
