It is useful to have this note.

I have previously understood that Paypal are more right wing than the Department of the Treasury and it is their preference to ban certain countries rather than obliged by law to do so. There is also some laziness, it is too onerous for the corporation to distinguish between firearms and cancelled stamps.

In general I think that Paypal is not fit for purpose as an international payment system, but I am still awaiting a widely available alternative free from politics.
