The guy is creepy and delusional.
He was spouting some nonsense about how I use leeway in a site's moderation to harass people, which I don't even do. I just speak up about the ramifications of not having a brain that functions like normal people, which leads to people I know online and even personally, making me out to be a huge laughing stock. But the ironic thing is, that he is actually the one using the fact the forums have no staff logging in to post with different accounts, including occasionally using my user names, as the one I typically use wasn't registered there beforehand.
It's not this alias. It's a character in a game, and just yesterday, he found my friend's YouTube channel. He always subscribes to my channels as well, with hidden profiles.
This 36-year-old troll has been known to me for over 18 years. He used to go on forums I was on too, around 2004. Since 2017, he has been doing this every week. But he posted a picture of himself using a gun on a firing range, and I got an IP address from Wikipedia, although an admin deleted the log for his edit. Because of that one New Zealand IP address, I found his Twitter account after looking up a guy I remembered from Australia, and he had a picture of himself and the same dog that he posted a picture of on another forum.
After that, he constantly denied being this James person. But it is him. Everybody else had moved on from the drama that occurred decades ago.
He also contacts film producers about me, just because I occasionally do extra work in films, which is a passionate hobby of mine, since you don't usually receive payment. He has, due to this side career, previously messaged a minister who directed a movie I had a small part in, as he makes media about his faith.
