Actually responding instead of instinctively downvoting, thanks.
I don't agree that what you described justifies a permanent ban. Many other communities use a punishment tier system, with cooldowns, that permit a reasonable level of moderation action per user.
The rules were strict on discord, sure, but they're relatively strict here as well (compared to the old subreddit). They've said they're planning to loosen the rules over time, but at the moment the same issues with users discussing in good faith being unnecessarily targeted is still relevant.
I know that for me and many other people, there was no reason or appeal instructions provided at the time of the ban. I had to run around attempting to contact several mods/admins (many of which ignored DMs or had them disabled) just to understand why I was banned in the first place and how to file an appeal.
The appeal process itself is also something that should be under reconsideration if democratization is a goal for this site. Sending an appeal form into the void with the hopes that one of the moderators that may have taken action against you would be able to impartially review the merit of your appeal is... not an ideal system.
