They def do that. I think what happens is, you make the account in year X when their anti-bot rules are laxer. Act hangs around, works fine. Then more stricter rules roll out in year X+5 or w/e. You login again in year X+5, suddenly you're violating the new checks. Boom, sudden ban.
The fuckers. I get that services have to fight abuse. And that's getting harder b/c of AI bots. And political influence campaigns and shit. But the colateral damage is HUGE. Ppl like you are getting caught in the crossfire.
