This is a bit old news by now but I learned it just recently, while reverse-engineering the change to a children's game.
Apparently, Brazil has banned recently the sale of loot boxes to minors in video games:

The game in question took a heavy-handed approach and just hid all the Shop offers for money from anyone residing in Brazil. On the one hand, this is good - the alternative would have been to implement proper age verification and deanonymization of players (although I suspect that the driver for this decision has been economical, not ethical). On the other hand, this eliminates some kind of service for players who are *not* minors.
