The one thing the Reddit Admin team (actual employees) takes seriously is people making new accounts to post in subreddits where they are banned.
Kill me for having a "porn" Reddit account and a "professional" Reddit account, I guess, plus one to disclose health issues I'd prefer to keep private... And deserve to. I actually enjoy anonymously helping people get through issues that for very good reasons they are also posting anonymously about (think: victims). This mentality ruins that, and I am now prevented from doing that.

Your problem is that one of the heads of your hydra caught a ban, after which point everything you do is assumed to be malicious. Given the political nature of what you were banned for, there is no doubt in my mind this is intentional. It's not an overt act of discrimination if they just don't answer the phone after "accidentally" locking you out.
For your own sake, move on. Reddit isn't worth fighting for. It's just a bunch of schoolyard bullies squatting on the playground equipment, throwing rocks at everyone and crying victim. If you're not a member of a protected class (or pretending to be), they don't want you there.
Meanwhile, I'm possibly one of the most Googleable people around (not due to fame, but due to nearly global name uniqueness) and it should be pretty plain to see that I'm a good actor (and kind of a big nerd) and that this might have all been a misunderstanding.
I'm kind of over it, but it is still hugely annoying. And it's terrifying to consider that no matter how anonymous you are on Reddit (and you might have very good reasons to be using an anonymous login), they in theory know exactly who you are.
What I'm saying is that AI could magnify a single human error in the past into an arguably massively unethical action; it could retroactively tie your anonymous actions in the past to your non-anonymous identity in the present. Where there is no escaping your past mistakes and you will always be punished for them, forever, by massive machines without any human intervention, or by systems in power that are arguably unethical and dystopian.
