Why is my Facebook account blocked shortly after registration?

Question

Facebook

I noticed such a strange thing: if you register on FB using mail in the RU zone, then after a while (minutes, hours) it asks you to upload a photo in which "your face is clearly visible." This is where the "life" of the account ends, no more reaction from FB is visible either in a week or a month. If you fight with a fake foreign IP address, a mailer from the same country and the corresponding name, then everything works fine. But this is not an option, VPN is a slow thing, like Tor, the page can load for half an hour. Who has experienced this?

And one more interesting point:

What's interesting? You don't understand how it works?
Scan your correspondence.
They will find all the addresses that letters were sent to you.
They will find users with such emails in their database
They will offer to add them as friends.
Regarding the fact that they do not store the password - do not believe everything that is written on the fences.
