Very possibly related to a politician, most definitely is a trap that cosplays as Gura at home. I don't see him post shcizo takes here, but his being SEA means he probably posts horrible things here but never uses an avatar when doing so. Gives minimal, albeit negative, response to meta-homo shit involving him, possibly uncaring of it.

Laughs at meta-homo directed at others, but did not react at all to the one involving him. Possibly completely turned off by it. On account of his Notice posting and IP ban subjecting him to permalurking, I feel like a he's newfriend or one who hasn't ventured far into 4chan. Good taste in /m/.

Either an unabashed schizo and retard, or a master shitposter with a sense of humor. The least gay of the writefags, on account of never writing gay stuff or entertaining the meta-homo shit in the thread.
Fluffanon
Classic meta-homo bait. A straight guy who does nothing but spread positivity and is constantly lusted after by his peers, forcing him go gently reject them. His demeanor, circumstance, and propensity for being associated with the pictures that he posts of his oshi reminds me of Ayamefriend from global - a more in-depth analysis by an Ayamefriend expert like Damascus would be appreciated. It's possible he plays hard to get and enjoys the attention.
Vampanon
Almost certainly the Dr. Jekyll to Archiveanon's Mr. Hyde on account of having similar tastes in everything and being manipulated by him. Likewise, he doesn't seem all too interested in meta-homo and doesn't post schizo shit, at least with his avatar / signature. One of the best writers.
Sekkusu
He's so fucking horny. How is someone so horny all the time. He's horny for girls, for fuck, for abuse and death. Incredibly enthusiastic about his interests. I kneel.
Tulpanon
As was pointed out, he seems like a chuuni who gets flustered when things don't go his way. IIIRC, he started the first real meta-homo fic and implied he's into feminization shortly after. Is definitely asking for it. He's a fandead so he's definitely a menhera as well.
