I’m sure this guy is a problem but reading this article and not bothering to go see his subscribed channels, I’m unimpressed.
Maybe that’s because you are not a pedophile. I knew a pedophile, and he LOVED to watch skimpily-clad young girls engaged in various activities. The latter didn’t have to be sexual; they just had to afford him different angles and views of the girl.
Voyeurism is a definite component of the condition. Have you never heard of guys sitting on a bench near a playground, just watching the young girls on the swings, etc.?
Take a look at some of the youtube vids he subscribed to. Videos of scantily clad pre-teens doing things that would be absolutely boring to normal grown men who have no interest in pre-teen girls.
