I posted a couple of time to batman. He seemed to be on the creationist side,and although I was arguing with him, there was nothing offensive about his tone.
I wasn’t here when the purge happened but I have a theory. There used to be a poster called medved (not related to the writer, I hope). He frequently posted a graphic bat, which he called Spifford. He was banned and has been banned again under numerous names. His arguments and writing style are very distinctive.
I remember medved for the reason you mentioned, the name. But I don’t recall anything in particular about him.
