Ok but genuine question why? Does in other countries payslip has any other more sensitive information than name, company and salary? Any more sensitive information than CV you attaching to recruiter?

Yes: in the US, your SSN (or EIN) is on every single paystub. (You could always manually redact it if some third-party asks for a copy).

By the way, another huge reason: images of paystubs can be and have been used by identity thieves to open fake accounts/loans, remotely.
