I have no idea. If I had to guess, I would say that index’s history pegs them as one of the accounts that posts almost exclusively “why the Democrats and specifically the Democrats are bad” content, along with being aggressively toxic to anyone who has anything to say about it, and they were banned for the toxicity and then proceeded to whine about it using whatever random bad-faith nonsense came to mind. In this case, what came to mind was the well-worn trope that the mods were brainwashed by liberal propaganda and were censoring anything truthful to try to push their program of getting Kamala Harris elected.

I don’t know any of that for sure of course, and I didn’t care enough to do more than a brief investigation. I just thought it was funny that they were applying reflexive accusations of liberal whitewashing against a target that was even sillier than most of the targets that it gets applied against.
