Last I checked, in China, you are legally required to put in your name and ID for games like mobile games. If I recall correctly, the law says something about making sure children don’t spend all day gaming. And just inputting a fake Chinese name and Chinese ID isn’t inherently bad. The bigger problem would be what the app does behind the scenes. That’s what I’d be more concerned about.
I’ve had to do this with PvZ2 Chinese edition back in 2021, which was originally started by PopCap Shanghai, so it wasn’t just some random small company making some relatively obscure game. I personally think it’s a dumb law, but there’s nothing a foreigner like myself can do to really change it.
