Really? I remember seeing GG in a mutual's plurk going on and on about the ship even as the mutual said they didn't ship it (or m/m usually. She didn't shut up and then started to post ship art, some of which was explicit without warning even as everyone ignored her. The mutual was clearly very uncomfortable. I saw her do it a few times to this person but this one time really stood out as embarrassingly cringeworthy and unaware of boundaries and no respect for someone else. I never had her added so I don't know how common this is and that's the only person I know who was her mutual but whenever she'd comment she'd say something really dumb and seemed to be incapable of understanding cues and subtleties and whatnot in canon and online. She gives me really bad second hand embarrassment.
