Seems like reddit's old reputation of being capricious and spiteful is still apt. Charming.
But they have someone once or twice a week look at a list of 200 appeals at a time, dismiss all 200 after glancing at the subject line of all of them together for 15 seconds, and then move on to the next page.
There is nothing they want from a 13 year old account. You're a liability. You still use old.reddit.com, they want to get rid of that without backlash. You want 2007's reddit back where you could have amazingly intelligent discussions on just about anything with dozens of other people who are essentially anonymous to you. They want to be Facebook, with ijits clicking on tiktok videos.
It's quite possibly they're just banning old accounts so they can re-invent themselves as a spammy Facebook/Instagram/whatever clone. You're in the way.
It'd be a mistake to assume that they're pro-bitcoin-scammer, when mostly they're just generically evil and want what you liked about Reddit to be long dead.
Combine that with the obviously hostile user interface. It’s a terrible terrible website and nowadays I don’t really miss it that much.
