A game made for kids should not allow sexually explicit material on their platform. And, in fact, they don't, this kind of content is very clearly and explicitly against roblox's content policy but they fail to enforce it.

Parents fail all the time, that's when the government needs to step in and take action, in this case by making sure kids can safely play the game. And I disagree, Roblox's entire business revolves around children, they make money off them at every step and they even pay kids to make content for their platform; they should be and they are rightfully being held accountable for what happens on their platform.
