Just a hunch that this could be a mistake of an overzealous community mod that thought that the nick Luigi Mangione was a troll... and that Evan Carroll is the best troll on the Stack Exchange network and he pushed the situation as he does and simply had the opposite effect than he thought he would ("Evan Carroll is flamebaiting again? There's no real problem, give him one year suspension" instead of "Oi, did someone make a mistake here here?")

Of course, I can be totally wrong but I've seen these things happen (I've been both a mod and a core dev at Stack closely working with the community team 8 years ago)
