Don’t Let Facebook, or Any Tracker, Follow You on The Web
I don't know from which country you are in but in my case they only asked me to correctly identify a couple of friends from 5-or-so photos. I'm no longer a used of facebook now for what it's worth #deletefacebook
Did you upload a photo already? I had not yet, but made a post that I was going to. I'm from America, it's possible they were being racist over my last name (it looks Spanish to people even though it isn't). Another thing, I was having problem with certain sections of the site, and tried on a number of computers and a number of browsers, before Facebook told me that there was a problem at the time being dealt with.
Same thing happened to me. Would not recommend if you must use Facebook at all cost.
