How to check validating Facebook users

A facecheck2.0.php script that its function would be to verify accounts on Facebook. I know there is such a script that can be useful for someone or his logic, I do not know who coded the “original” had no references, so I internally put a comment on the day of the Edition.
The script was almost “functional”, but the request form was not correct … and also blocked easily by facebook.
With this I added random user-agent functions, proxy, proxy list, proxy-tor, modified the request logic and a middle “priv8” validation that I debugged in the Facebook request until I found a different way to validate the login.

Usage

1. Download facecheck2.0.php script
2. Run
