Tell HN: Facebook's reasons to disable an account is a blackbox

Recently i tried creating a whatsapp developer account, which essentially means i have to create a Facebook account to login.

As i was trying to register for the first time Facebook showed a message "We've reviewed your account and found that it still doesn't follow our Community Standards on account integrity. You cannot request another review of this decision. To learn more about the reasons why we disable accounts, visit the Community Standards."

When i clicked on link "Read more about account integrity" it took me to a page, where it showed error "This page isn't available at the moment".

In overall it blocked me for a reason which i will never know!
