This is all anecdotal/first hand stuff, so feel free to take with a grain of salt because I just couldn't be bothered to make archives at the time, but Trunchbull, in general, is a really bitter and vitriolic person who loves to jump head first into drama and then cries foul when she gets disciplined for it. Jasonafex can't animate? Better go troll the shit out of him and respond to his comments on other, unrelated people's pages. Get banned for trolling? Dragoneer and the mods have it out for her. Even outside of that one instance, she's had a chip on her shoulder in regards to Dragoneer for years, having said so herself on Lulz.net and alluding to some kind of relationship the two had involving a previous account of hers that she refused to divulge; she was gloating to high heaven over Sciggles dumping him.
Dragoneer is a piece of shit, absolutely, but it's hard to take the word of someone who has made it perfectly clear, has no love lost for him and has made a point out of enjoying his misery. Also, Dragoneer has pictures of himself in his own gallery and they've been posted across sites she frequents, how can she not know what he looks like?
