I handled the “real human” problem by charging access to the platform (and doing something socially responsible with the profits). Saw recently that X is starting to do this for signups, which feels icky (and likely explains why my idea didn’t take off).

X has been doing this and it didn't seem particularly effective. There are still many bots on the platform.

Also, someone with a lot of money can still get around this requirement.

Bribing a government to get fake passports is possible, but many orders of magnitude more difficult.

Bribing hotel clerks to make a new account every time a guest checks in and hands their passport over might be easier since in this case you just need to scan once to register. Maybe that sounds impractical and low volume but imagine you own a chain of hotels across thailand or whatever, you could probably make thousands of accounts a day and just sell that as a service.

Yes, that's just another problem with using ICAO biometric travel documents for something they have decidedly never been designed for: They don't have any PIN code protection, unlike some national digital ID schemes based on similar technology.
