Social media pitfalls

Published: Saturday, June 1, 2013 5:30 a.m. CST

To the Editor:

It always amazes me when I hear folks complain about what is known about them by marketers, government, employers, co-workers, etc.

How do they know? You told them on social media. You thought you restricted the information, but your “friends” allow those you do not even know in their network to see your information. Once posted, you no longer control that information.

Social media companies allow “researchers” to data mine your postings and then sell that information to marketers. Is this legal? You gave them permission when you agreed to the terms and conditions.

They also create sophisticated algorithms (after combining all of your postings to build a profile about you and your friends) that try to predict what you and your friends might be interested in pursuing next.

I am sharing a very small fraction of what they do and who sees your information. Those with children should be especially vigilant. They are the ones that will divulge not realizing the possibilities.
