It happened to me a long time ago. He was not only spamming and using SQL injections to destroy my community, but also advertising his own concurrent website. When I also started to build scripts and destroyed his own website, he basically realized the harm he was doing, apologized and stopped. Reminds me of the old good times when you could trap script-kiddies on msn. "I think you are lying and not capable of hacking my computer. I'm waiting for you, my IP is 127.42.196.8"
