Not sure I'd say you have it right when your characterization of her as a scam artist is pretty unsubstantiated. Let's call it your working theory for now.Do I have this right?
Creepy dweeb streamer with money convinces another community streamer he wants to have sex with to come to an event completely on his dime. He peppers her for sex, she plays along all the way up until she gets there.
When they get there he's ready to get busy but she's not about that life. He acts like the dweeb he is because he feels he got played for a free trip (which he probably did) and he acts like a complete douche. Then he gets kicked from the event for being a creep.
He's still upset he got played and that he couldn't get his "choke her out" sex on, so he goes online and then plays himself for everyone to see.
Who raised these people?
