Facebook Roadblock

When using a proxy to access Facebook, there is a chance to get a roadblock from Facebook for security reason. It's good. I have no problem with Facebook Roadblock until the new change on Step 2 today.

In order to proceed, Facebook needs to verify that you are the owner of this account. To do this, please identify the people tagged in the following series of photos.

To pass, you cannot get any answers wrong. If you aren't sure about a question, please skip it. You can only skip 2 questions.

I have more than 500 friends, most of them are my game players. I don't pay much attention to their photos. How do I answer all 7 correctly?

I locked out by Facebook for a day. So, either FB goes back to old way to authenticate user or people don't use FB. That's it.
