Facebook has made changes throughout its lifespan from user interface, to the addition and removal of features, to policy changes.
In 2015, it was reported that a growing number of Facebook users are being wrongfully and inexplicably suspended from their accounts by Facebook to give up copies of their private identification information.
If such information is not given up, users suffer permanent restriction from their accounts with no alternative way of retrieving them back.
The private identification being summoned by the website from its users include copies of their driver's license, state-issued ID cards, passports, military cards, photo IDs, etc.
This has created great displeasure for users who practice discretion with such information.
It's also worthy to note that Facebook does not require the release of such information when individuals sign up for the site.
With this kind of personal information having the potential to seriously harm individuals, the method has been described by users as a presumptuous, dictatorial move and an offensive invasion of privacy by Facebook.
Other popular websites have only asked for verification of identities through an e-mail confirmation link, or in some cases, a cellular phone text message confirmation.
In 2010, the Electronic Frontier Foundation identified two personal information aggregation techniques called "connections" and "instant personalization".
They demonstrated that anyone could get access to information saved to a Facebook profile, even if the information was not intended to be made public.
A "connection" is created when a user clicks a "Like" button for a product or service, either on Facebook itself or an external site.
