TBH, I tend to agree.This thread should not even exist.
I asked last week whether the mods have a mechanism to issue a notice in a way that cannot be replied to, and Slowster actually did that at the initiation of this thread.
IMO, it would have been wiser to leave it at that, a notice saying that someone had been barred, and why, ideally referring to the forum rule that they transgressed, full stop.
That wouldn’t, of course, prevent anyone opening a discussion of the rules, or moderation practice, in a new thread, but it might at least have minimised back-references to the individual.
