Pretty sure it was his character name. I mean, maybe he was running around before that calling himself Tigole Bitties, but that seems more like a spur of the moment thing at character creation. People name toons weird crap.
And ultimately, this.
My point was more than Blizzard Corporate said “that’s fine”. That coupled with all this news adds up to not looking great for Blizzard’s Work Environment. I don’t think Kaplan has been cited as an issue (though no one is really being named, so time will tell). I think it’s more that a corporation would okay that moniker at all. His name is distinctive, he could’ve been Kaplan or the like.
