A recent interview with a Facebook employee on The Rumpus blog here raises many concerns about the information that Facebook keeps on its 250 million or so users. We outline some of the highlights of the post below.

1. Facebook Saves Things That Have Been Deleted

Whatever status updates or unglamorous pictures of you are still inside the server somewhere. A word of advice, think carefully and be tactful when uploading photos or making a status update.

2. Facebook Knows Your Viewing History

Log of clicks are used by Facebook to determine your viewing history. Hence, it knows whose photos you are going through.

3. Facebook Knows How Often You Interact With Or Click On The Profile Of A Given Person

Depending on the number of visits you made on your friend’s profile, Facebook uses this data as a method to judge who your good friends are. This is visible through Facebook search where your friends are not listed in alphabetical order but by the people who you interact most with.

4. Facebook Carries Out Psychological Tests On New Features

Instead of doing group sampling or beta testing on their new features, Facebook does the above plus eye ball tracking to get an idea of where you are looking at.

5. Facebook Employees Are Able To Retrieve Any Message You’ve Sent Out

Since all data are stored in the server, employees have the clearance to pull out any data about you through a simple query on your profile.

There is some doubt about the authenticity of the interview. However, what is clearly beyond doubt is that all of this is credible and there are no guarantees what is being done with your private data. You have been warned…
