Not to diminish the disgusting actions of JF, but JF never uploaded the conception footage of his child to own the a-logs. Ralph deserves all the attention he gets, and it's not just due to his history as a mediocre streamhost. JF and Gunty are apples to oranges, though, even though both are definitely manipulative people who predate on young, vulnerable women.
I would say that the Gunt is less sinister than JF, quite possibly because he is so trashy. There's a sense that Gunt is what Gunt does. He simply doesn't know any better and is so pathetic that he really can't do any better than picking off his mentally deranged fans. All Gunt cares about is getting his dick wet. Everything else is incidental.
JF on the other hand has a disturbing intentionality about him. JF doesn't even need to go after the mentally handicapped to get pussy, but he does anyway because it's what he wants. He specifically targets mentally incapable women. He enjoys being able to hold all the power in the relationship and having someone completely at his mercy. Pretty fucked up in my humble opinion.
