You doubt the seriousness of the Witch King of Angmar? The Pale King? The man leads a dark host of fell origin! He wears a ring of Power! His threats are clearly entirely credible, it is only a small step from posting on the Fediverse to a siege of the White City and the deaths of a multitude.

Yeah. For the life of me I don't see how someone could see a credible threat in that post. The man could actually murder Fink the same day and the post still wouldn't be evidence of a credible threat; it is just too silly. At best it is evidence he is deranged in addition to the trolling it turned out to be in this case.
