Not to be that guy but Eva doesn't actually have an Instagram. There's a bunch of kids pretending to be him, though. (If you notice, he has a distinctive way of typing and that Instagram post isn't the way he talks at all.)
Someone on KiwiFarms found many important volunteers (models, animations) are minors. The official YanSim website says not to volunteer unless you're over 18 (nope) and have professional experience (they probably don't, but there's always exceptions).
Don't you love when the sub says "stop all the 'look at yanderedev's past, you should hate him!' posts, stop the drama" but all the posts don't even talk about his past (which breaks a sub rule) but actual current stuff affecting the game that he did here and now and all the "drama" is valid concern from the fanbase?
A bit off topic but I've noticed YandereDev went from "stop asking me questions" to happily answering stuff on Reddit. To be fair, the "stop asking me questions" might have actually been "stop emailing me questions" and I could be remembering wrong.
I would check if any emails are spoofed, because there's always a chance someone (like FairyTailFan who joined KF a while back) tried to impersonate Dev to harass you so he looks even worse. Even though that's not necessary and just makes the anti-Dev side look like nasty troll haters. The emails he sent regarding the contract and everything are probably his, but anything from your exposé out could have not been from him.
To be completely fair @swoomzie you did use aggressive language, which hurt your chances. I don't think most people would want to form a contract after being called out for something, especially if you're right.
Armchair psychology alert: fans like to think Midori represents the "bad" fans by constantly emailing, and since they don't there's no way they could ever be such a Midori! She's cute, and she lets the fans have someone to dislike while affirming there's no way they could ever be that bad - someone to feel superior to.
So you think my edgy idea is distasteful? It doesn't fit? Just plain don't like it? Must be because you're a triggered offended SJW! Something makes you uncomfortable? I don't have to pander to your feefees! Aka every edgy idea is only rejected because SJWs or morality police and not because of anything reasonable like "gratuitous edginess" or "it doesn't fit" or "it doesn't make sense."
I don't think this one was a stolen model, but it doesn't look refined or princessy at all, just... wrong. Her hair looks like caterpillars or worms. Is it just me, or does Kizana's voice sound too old, mature, and smooth for a high school girl?
I keep seeing this, so I just wanna say... There are multiple problems with Osana, but she's probably not the martial arts club leader or a former one. That was just a fan theory that doesn't really seem to fit with her "incapable" or "weak" self defense (I forget which one it was). The theory exists because Dev said a new line about Budo Masuta inheriting the Martial Arts club from the previous leader after defeating them and something about having a crush on a girl has something to do with Osana. More likely, Budo wanted to impress Osana or something else, but I really don't think Osana is the martial arts club leader. Also, Kizana's hair model and profile picture looks awful. She doesn't look regal or princessy, just weird.
Fairytailfan666 usually defended Eva to the bitter end but got disillusioned somehow and made an anti-YanSim subreddit already linked here and joined KiwiFarms I think as princess1234567 or something similar. (She previously had an account there as crazypie132 when she was still a fan.)
