Banning somebody's IP address, whether it's a proxy or their own ISP issued subnet, likely won't do anything. In this day of age, there's so many free VPN services available, that it's so easy for abusers to keep on coming back. Hell, even Opera has one included. For every IP address you block, they can come back within minutes with another proxy. So if you added 82.* to a block list, you'd be unfairly banning any normal users with that IP range.
Unfortunately, this guy is either in Australia or New Zealand, so my country's jurisdiction could be separate to his. It's possible he is in New Zealand, as I obtained an IP address on Wikipedia once, to do with a company named Spark, which doesn't cover Australia. Unfortunately, I just ran in circles trying to report him.
I know who he is, however, because he happened to be spamming on Biohaze in 2017. He posted a picture of himself and a dog. Not long after that, he went on Wikipedia to revert my edits, and I got that IP address in question. So I thought of people I knew from either Australia or New Zealand, and I found his Twitter, where he had a picture of himself and the same dog. And I even remember his old handle from when I knew him back in 2004. He was also a moderator for The Horror Is Alive, run by Dot50Cal.
Since 2017, he has been annoying me on tons of forums and the Fandom wikis. For some reason, he creates multiple pseudonyms on the Horror Film Wiki, to edit articles I edited months ago, even with anonymous IP addresses. After that, he closes them and signs up even more. He probably looks at the recent changes menu, which is rather creepy.
Apparently, editing the pages automatically subscribes users to the pages, so if anybody else edits them, they get notified through emails that such and such has edited, whatever it is. I'm not quite sure why someone would do that, other than to stalk me. My mother advised me to avoid him, but it's not very easy to do that unless I just stop using these websites altogether.
He may have also tried to contact actors I met ages ago, which would not surprise me, considering he gives my address to women on Twitter. Somebody gave me a copy of a film I had a small part in, and I uploaded it on Internet Archive without the guy's consent. So he was there too, and I think he informed the guy that I did that.
He was on one of my streams in January, using dumb or offensive sounding aliases like "Retard Check" and posting my address on air. Some of my followers are wanting me to play Resident Evil Village next month. Although it may be a bad idea to stream it publicly in case he comes back, spamming again.
He knows I know who he is, which is why he makes videos like, "You think you have this figured out, mate!" Because well, I do...
