Yandere Dev - also known as Alex Mahan - is a 35 year old game developer who has groomed a 16 year old girl by the name of Jane (not her real name).

More information is coming out day by day and every day he seems to continue to get away with it. Boycotting his game won't help but taking away his only form of income may possibly be. His influence online as well as the game he uses as his shield won't last when he hasn't got his fans' money to keep the game going.

A reuploaded video of the evidence​ 

Alex's response to the situation

The 30 minute video goes into heavy amounts of detail on the situation with evidence from the conversations between the two. It's reuploaded as Alex copyright claimed the original video as a way to censor the outcry. The two photos are great examples of the way he thinks, too. Both speaking of hypothetical 16 year old teenagers' breasts and them wearing bikinis. His response was the worst, too. 

So all in all, I just wanted to cave in on this all and make an outcry to Patreon to take him down. His fan base is full on minors and I don't want anyone else being hurt.
