All I remember from the Interspecies Reviewers drama was this absolute goofball who would show up daily in my discord server ranting about how "they" were trying to take away his animes or something. Everyone present just went "Jesse, what the hell are you talking about?" but he was never able to explain what it was that he found so sinister about the situation.
Best I can gather, he seemed to believe there was a conspiracy to suppress Interspecies Reviewers, and that Funimation and MyAnimeList were both a part of it. To what ends this conspiracy was working towards, I can only speculate.
He was later banned for trying to use the discord as a dating site. He was looking for women in their 40's to hook up with. Strange lad, I hope he's feeling better these days.
