Forum:Help with an abuse filter?

Hi, I'm an admin on the Some Ordinary Gamers wiki, a creepypasta wiki. Over the past couple months, we have been dealing with a chronic spammer with a proxy who has been incessantly socking in order to upload spam pages. In response we created an abuse filter that prevented page creation by non-AC (new) users. The filter worked for a little while until the spammer figured out that it did not prevent non-AC users from editing pages and turned to vandalism instead.

His attacks have slowed down and we have managed to control the damage he does pretty well recently, but just having the filter up has been a major detriment to our wiki. We have had a significant drop in traffic due to it and the community has suffered a drain in energy and enthusiams. In effect the spammer seems to be winning by making the wiki a less fun place for everyone.

I have an idea for an abuse filter with a rather specific set of conditions that I believe should frustrate the spammer enough to force him to move on to greener pastures and continue to help us fight spam and vandalism even after he is gone. But I don't know how to program it. I was wondering if you guys could make such a filter for us if we told you the conditions or hook us up with someone who can.

Thanks
