I think there's a major player here that most adults overlook because it's a bunch of kid-created nonsense: Roblox.
This platform is absolutely rife with gambling and scammy currency-spending mechanics, and all of this is directed towards children. You're constantly bombarded with pay-to-win, pay-to-cheat, pay-to-play, one-arm bandit, "donation" requests, "invite your friends to unlock", literally every dark pattern you can imagine... all on top of near-constant copyright and trademark violations.
I'm entirely convinced that this platform only exists because it's too annoying for adults to even scrutinize too closely but they pull in huge amounts of money from this stuff.
