I agree that your hypothesis seems likely. You can see a sharp shift in tone too, between “LLM-style” essays and then sudden abrupt uses of stuff like “lmao” and smiley faces “:)”. I’m surprised they’ve been able to avoid being banned, but I guess they seem very focused on skirting the rules by the letter of the law. I would argue they don’t engage in good-faith arguments, but maybe that’s not bannable, what do I know.

I still can’t say for sure whether they are intending on promoting third-party voting for political reasons, or if they’re just addicted to arguing online and have found a fertile hunting ground.
