I would actually be very interested to hear from a lawyer—or at least someone with legal knowledge—why Roblox hasn't been prosecuted for this. These children are creating value for the company, and they're being compensated via a currency which can be converted into dollars. How is that not payment for work?

If Robux could only be converted into Amazon gift cards, I would still argue that was a labor violation, but I could at least understand why the case was murky.

Can Uber hire 16-year-olds to drive for them without a work permit as long as they're paid in special UbiCoins which are converted into dollars later?
