Facebook is and always has been a data collection site .
You can check from cmd prompt and you can view the connections to your computer from facebook.
Like all government controlled infrastructure, they are full of flaws, this happens to one of them.
Currently, the data collection centers are being over loaded and there are an increasing number of faults as a result, however, new data centers are being built around the world. This should help ease the burden. If your wonder under what pretense they are being built, it is companies such as Telus, Shaw, Bell, AT&T and others calling them everything from "Data centers" to "communication banks". There is a new one being built just 1/2 mile from where I am, boasting 5 terabytes of storage per cubic inch in a building with 500,000 square foot of floor area per level.
Thats a hell of a lot of data to be stored for Telus customers...
