Not understood. There may (or may not) be an argument to be made about the difficulty of sorting between trolls and those with unusual but accurate knowledge, but you haven't made that argument. I'd be interested to hear it, but you've gotta make it. I've never seen a never-ban policy and can't believe it would work; the conduct of genuine psychopaths online can be truly extreme and not just uncivil, but designed to prevent the forum from functioning. Persistence-bullying is one of the nastier forms this takes.
