It may be true that you got banned for ridiculous reasons, I have no way of determining that, except by hacking your used instance and Reddit, comparing IPs and other identifiers and identifying your accounts, but that’s too much work and illegal. Or you can provide the account, but that probably won’t help much anyway, as I don’t have easy access to Reddit myself, because of different reasons.
I don’t think that everyone that gets banned is a racist/terrorist/🌈 hater hybrid. I also didn’t say that you have done that. The ToS encompass much more that just hate speech, you may have started a DDos for example, I don’t know.
Of course Reddit doesn’t just let you onto their platform again. You may have a chance to get unbanned if you talk to their support, but a permanent ban often stays permanent.
I agree with your “fuck them”, but for different reasons.
