My assumption is that Vito does it because he believes, mistakenly, that all attention is good attention. For a normal person, he or she might realize that saying they're a pedophile might be a bad thing; Vito, on the other hand, believes it's going to draw people to check him out. "This edgy comedian is saying he fucks kids, how edgy! I better check out his Patreon!"
In my opinion, Vito's attitude of "all attention is good attention" makes him worthless. He has no principles, he has no original thoughts, and he has nothing to say that's worth hearing. Does Vito style himself as a comedian? Because I don't think his jokes about him being a pedophile are funny. Hasn't he in the past done political commentary? If all he ever does is say a bunch of shit in order to make people mad at him on the Internet, it all goes out the window because he only says what will get attention. Then there's the whole flagging YouTube Twitter in an attempt to get another person's channel deleted.
