Proof?
The story going around reddit was that he passive aggressively sent an ass pic to a guy in a “kiss my ass!” Kind of way. It wasn’t sexual. The guy who received it was like “wow gallowboob im a minor, How do you feel about that?” Or something self-aware like that.
There is no proof other than that, that the pic receiver even was a minor. He could’ve just been using the anonymity of the internet to his advantage. Or he really could’ve been 1-17 years old. Either way, the pic wasn’t a sexual “hey lil mama, see anything you like ;)???”
But Reddit doesn’t like him so everyone who mentions it is being intentionally misleading.
