Mostly yes: In a sense, doing anything "permanently and forever" is a big deal. People can change and grow, and a full permanent ban without any opportunity for appeal seems harsh. Very few things should warrant a permaban: one example that comes to mind is willfully attempting to circumvent a temporary ban. Posting spam, too.
Also no: Lemmy isn't and shouldn't be a critical part of anyone's life. If you were forever banned from it, maybe it's okay.
While I generally agree with you, I think we have to look at it from the moderators' perspective, too. What are they supposed to do? Deal with the same persons every few weeks until hopefully some of them grow? Moderating a community is already a lot of (often thankless) work. I don't think adding this would help finding and keeping good moderators.
Ultimately it's not only about what is the most fair but about what tools are needed to keep a community running.
I always want to spite them by evading but they catch me each time
I got banned permanently because of a horrible mental health episode like really I'm not like that 24/7 and my normal post history showed that. Now if I was brand new and said that stuff I think a warning or one week ban is better
I suppose they have yo deal with a lot of stuff so after a while they just can't differentiate anymore and it's easier to just ban people than. Being considerate takes effort.
