THat's how their whole "Appeal" process is now. We had accounts suspended permanently for daring to question the mods at a large subreddit, and they nuked every account that logged in from our home IP. Wife's account, which was innocent, was permanently suspended. Same with housemate behind us that used our WiFi.
The appeal process? Within 5 minutes we got a useless and canned message that was along the lines of "After careful review, it was been determined that... blah blah blah."
We've since made new accounts, but it was 100+ days later, and all of our reddit usage is way down as a result. My account alone was 8+ years old. Gone, no appeal, nothing.
Reports in /r/help were that they used AI to handle appeals. Not sure if it's true, but it feels like it is.
Maybe they saw your "it was my neighbor on my wifi, I swear!" and reflex-nuked.
Also, mods don't suspend accounts, employees do. From user reports. Then admins reinstate or don't.
I wouldn't put it past them to auto-nuke any appeal with the word neighbor, though. That's the "my dog ate my homework" equivalent of trying to get out of a warranted ban.
To be fair, that's still possible (and sometimes the case) with human moderators, though I find that experience to be exceptionally rare, and the remedy (just don't use that subreddit) easier to perform. At least if the mods of some sub go haywire, users can always create another sub. With widespread use of AI moderation, there'd be nowhere to go to escape.
