Yea, I didn't explain the story:
This guy discovered my signature on another forum, and decided he wanted to use it.
So he linked directly to it. I was playing around with cpanel, found the raw logs from the server, and saw requests for the signature from different forums, ones that I had never registered on.
I went to the links the logs gave me, and found someone using my signature there. I got pissed, and edited the signature script so that if you were coming from one of the sites he was using it on, you got a goatse picture with text telling everyone what had happened.
One forum just removed the image. The other nuked his entire signature.
