I had a similar account that got banned for connecting to the wrong VPN endpoint. Clicked a random server from my VPN provider, suddenly my account was permanently banned with no ability to appeal
Thinking it was just some issue on my end (it was a non-standard looking ban), I logged into another OG account of mine, which also promptly got perma-banned
Extreme incompetence for them to be issuing perma-bans like that based on IP address
