There's an instinct in many of us to destroy and pervert, and it can lead to very dark places.
They aren't trying to pervert the children. This isn't some cabal.
It's just money.
It's just people trying to get children's eyeballs to collect minuscule ad revenue.
It's the same as the people who abuse their kids for a Youtube channel, or the russian companies that put out 10 """DIY""" shorts a day which are just fake.
Youtube rewards constant churning content creation, so that's what is done
They do it because it actually works.
