I’ve dealt with someone like that before.
This dude REALLY liked Starlight. He liked her to the point where he’d actually go out of his way to edit artwork without permission, just so he could turn her into a mouthpiece about how “she and Trixie/Sunburst were just friends.”
There’s also the fact that he preyed upon a minor who used a Starlight Glimmer profile picture, which really pissed me off.
I think he might’ve gotten banned, but I’m not 100% sure. All I know was that it was very unsettling.
