Copyright notice is in vboptions and takes a statement. If you have a terms of service statement, it probably explicitly states that posts are the property of the forum and covered under the forum copyright not the poster. Usually the terms of service agreement is full of weasel words that avoid (and cover situations exactly like this one) any culpability by the forum owner. But you are forgetting something, I think. Your forum has been indexed by many search engines and spiders and content scrapers. Just because you delete it from your server (I would not btw) that doesn't mean it gone so he's pretty much screwed on that account and you have no control over that piece of the pie. Unless you get something from a verifiable legal entity, you don't have to do anything but ban this morons and his IP address and do not under any circumstances correspond with him in any forum. In this case blackhole is best.
