Yeah, while these questions have mostly been too ridiculous to be considered, repeatedly asking what precisely warrants a ban sounds like you’re looking to walk that line.
Just don’t walk the line and don’t consider your wildest Reddit experiences as that line.
In particular, there is no point in asking these questions, because as we already elaborated on the first post, no one knows what will get you banned from individual communities or instances, since there’s a lot of different humans involved in the decisions.
But the community is smaller, so if you’re posting good content and interacting with people in a friendly way, the moderators will likely know you and gladly give you the benefit of the doubt.
