I don't think he was even a troll. Just very deeply disturbed. The conversations he had with himself were always very innocuous. He'd usually have a bunch of back and forth with himself talking about track times. Not even conjuring up any fake beefs with himself.
I was cracking on Herndon, stb, 1953 for chatting with himself years ago on here. It was so obviously the same guy, and he’d carry on conversations with himself. I called him on it a few times a couple years ago.
