They don’t care, and I’m have a feeling that the app will not put up with nonsense from foreigners. This is not a Meta subsidiary, don’t forget.

As an example (as others have mentioned on here) that your country (or province, if inside the PRC) is shown on your profile cause of all the trolling from the Taiwanese.

If they need to ban Americans I’m sure they would, but why do that when you can just moderate them? At least give it a try…
