TLDR: The r/selfhosted subreddit has a Discord server. The owner’s account got hacked leaving the server in a precarious state. They submitted a support ticket, but Discord has not taken action in weeks and probably won’t at all, so they are considering starting a new Discord server.
If a little light sarcasm is incivility to you, then you’re in for a real struggle. I don’t know how most people end up self-hosting but I suspect it’s more of an organic process. For me, jeez… I can probably trace it back to using StumbleUpon browser extension, hearing about Linux, then installing it as a way to avoid studying for exams. Once I was using Linux on my computer, I suppose self-hosting was inevitable. Where did I get the info? Wherever I could find it.
