I looked at Roblox recently as a nostalgia trip as I was active in the community over a decade ago when I was a kid. Genuinely insane that it's legal. Full dark gambling patterns, insane access. I think the only reason it's not been regulated is that people haven't looked closely, but it's as if someone took the worst of gacha games and decided to base their childrens platform on it.
Tbh making Roblox illegal feels like the same moral panic that our parents had around metal music, hip-hop, and arcades. My kid plays Roblox, I prevent her from talking to others, and I police the Robux purchases. It really is a fun platform. The problem is for parents that aren't technical, or are negligent and don't know how to police it.
I feel like this argument has become a cliche in itself. Sometimes things are worth panicking about, and limiting access to things like cigarettes or gambling for children has been a real benefit to society. The same could be true for the dark patterns listed above.
