Probably so.
But none of this gets to the root of the issue with GM Widower’s recommendation: if Diantane is freely allowed to spew his own garbage, why are we being admonished for responding in kind? Idk what you know about humans, but we get awfully hung up on issues of fairness from authorities.
You can say “don’t respond” all you want, but, on the forum I briefly mentioned above, that moderation strategy led to significant departures by core members, because it was made abundantly clear to us that the troll was not to be admonished as we were; this was just a rigged game for them to exploit indefinitely while respondents racked up bullshit warnings that were, for good reason, not particularly respected.
