List of countries that cannot make a PSN account, following the Helldivers 2 controversy.
(programming.dev)
The censored one is probably Niger
UPDATE - special thanks to @dditty@lemm.ee for making a map showing the countries without access to PSN:
The only data they can get is what you already share in game. And a little portion of what is on Steam.
You obviously have to give them whatever data is required for a PSN account. You could give them fake personal data of course, but good luck remembering your fake info if you ever need to reset your password.
