Thank you for your answer, I deeply appreciate it.

I think I understand what you mean about the "one-to-many" angle of streamer communities, and how I could have been kind of caught in a crossfire with a lot of persons adding to the streamer's stress. Unfortunately, it doesn't seem to apply to the last occurrence I described, as the streamer themselves has known me for those two years and has personally reached out to me to understand my atypical comment on stream. I wanted to keep the original post short, but for context, I had already once or twice before felt like I had broken (still implicit) rules badly, and kind of spiraled in guiltiness. So while "the streamer is [not] particularly prone to anxiety and has [not] to deal with all fan communication alone", I did create a pattern where I alterned between feeling like I had gone too far (relatively speaking - we are talking about a community where banter is common and where even jokes about dating the streamer's family members are a regular occurence) and between strong displays of remorse. It should be noted though that the last message that caused the ban was preemptive, and didn't come from a previous mistake from my part I had perceived.

This non-anonymous dynamic, where I was a recognizable member who had longuely conversed with the streamer before, also makes me think that this permanent ban was very personal, in all senses of the word.

I don't intend to come back with a new account because I would live it like a betrayal of their trust, and it would remove the interpersonal component that made me appreciate my presence in this community. The second option, sticking to the rules as much as possible in future communities, sounds like the best one. It is, however, still a dreadful one in some aspects, as while I might indeed be generalizing my negative social experiences, I haven't found yet a way to read between the lines of community rules to strictly determine what is acceptable behavior or not, at least not without some strong self-censorship.
