I might have mentioned this previously, but you could just require the first post by a user to require approval by an admin or mod. I think that the StackExchange forums require this. Prior to this, you could also get a bot to parse the post to check for duplicates.

This thread started in 2008. I think the forum is much more secure now.
The few spam posts there are nowadays, we moderators can handle with relative ease.
