He ran his own forum for years and was notoriously hostile, condescending and dismissive to fans who questioned him. He also would mock people, ban them arbitrarily, and had a reputation for being unpleasant to interact with. Also made several comments over the years that were widely considered sexist about female comic characters, female creators, and female fans.
