Looking at your modlog, I only see 3 actions:
https://lemmy.world/modlog?page=1&userId=12206547
The first is something about tailscale, but it doesn't show me what community it was removed from, so "Rule 3" isn't a lot of help.
The second is a post asking about how to reach the mods, which a lot of communities would remove as a "Meta" post.
The third seems to be in regard to your response to "What do we do about Elon Musk?" and you responded "Luigi" which is a direct call for violence, that goes against lemmy.world TOS.
Seems extreme to jump STRAIGHT to a perma-ban for that one. I, personally, would have just removed the comment with a warning, which is weird that the mod didn't even do that. If the comment was bad enough for a perma ban, it should have been removed too.
I'd reach out to the other mods in Ask Lemmy and see what they think. They may just be overwhelmed with violent content currently and are taking no prisoners.
