Personally, I think the fact that he goes after fans of his work does make him a predator. He knows that they like his work, and they're probably starstruck to be talking to the voice actor behind one of their favorite characters.
He's not DMing e-girls or like Instagram models, he's not creeping around on dating sites to get some trim on the side. He's DMing hardcore fans of his characters to get sexual content from them. He's targeting people who would react the most enthusiastically to him, and he's keeping them on the hook by performing his characters' voices for them and talking about the characters they enjoy. He's using his relative fame to manipulate his female fans into sexual situations.
You can't throw that back on the women he's targeting because "they're all adults! they should have known better!" - if you're targeted by a celebrity who makes you feel special, who appeals to the aspects of their fame that appeal to you as a fan to lure you into a sexual conversation, then you're being manipulated by someone who has power over you and who knows they have power over you. It's not okay, and Quinton Flynn is absolutely in the wrong for abusing his position as an entertainer over his fans for his own sexual gratification.
So what you are saying is he is doing what literally every single famous person throughout all of human history has done?
