I think that if Untherius actually cared about anon forums, he would know exactly why his fic is inappropriate and not well liked. So either he visits and doesn't give a shit, knowing his recipient is unlikely to be pleased by his bad faith gift. Or he doesn't visit. Either way, I don't think that there's anything wrong with the recipient leaving a nice comment on the off chance that he doesn't visit and complaining about their very justified grievances here.
