verify account after send friend request

Hey, how does it work now? I used to be able to send up to 40-50 invitations a day and write to users, the only thing I received was a writing block. Now at fb account I can make 30 invitations without a problem, and at the other account I received a 'selfie request' after 15 invitations. Accounts over 5-4 years old. What is going on? Why such a change? For 2 years there were no such problems.

I am having this same issue. I send 1 friend request. Yes only 1 and I get the PV then photo verification then ban.

Cant figure out wtf im doing wrong to cause this after only 1 friend request.

today i send invite to 1 (!!!) group and fb give me selfie verificaton, stupid facebook!
