Have you appealed it? I did that this morning and immediately got a very brief, standard response: "Hello, your account was suspended due to violating X's rules. After reviewing for reinstatement, your account will not be restored. Thanks, X"
That was IT. I emailed back with more of a personal statement than I'd given in the appeal form, saying I was a long-time user, had a variety of interests and followed a wide range of accounts (true), that I enjoyed engaging in debate and discussion, that surely X's lifeblood was its users and the ability to debate, but that debating entails opinions, and that I didn't think mine were at all reprehensible.
I got a slightly less depersonalised reply: Thank you for reaching out about case .... This case has now been closed and cannot be reopened, but we want you to get the help you need. Here's a link to our Help page or you could open a new case.
So ... maybe I'll do that. I replied, again asking for some concrete details of what they thought I'd done to violate their rules. I will be ASTONISHED if I get a reply.
I'm definitely too fighty on social media so maybe this will be a lesson to me, but I'm also outraged that there's so much toxicity on that cess-site, horrible threats to women, porn images, far right rabble-rousing - and in all probability I was reported by a TRA who's done their fair share of toxic posts. Who knows?
