How do we know who and what payments are blocked by PayPal?

[BoStor]

I understand that PayPal refuses to send donations to Medical Aid for Palestine (MAP).
Is this correct and why would such a reputable charity be blocked?

Paypal is not available or supported in Palestine.

Medical Aid for Palestine is a UK-registered charity based in London which works to provide health care

to Palestinians who need it most in the illegally occupied territories.
