I logged onto Facebook this morning, and I was immediately presented with a sponsored display ad hawking a t-shirt design that read, “Never underestimate an Old Man who listens to Neil Young and was born in September.” If I was naïve, I would see that ad and think, “Wow! This is my perfect t-shirt”, then order one. In the short time in which this ad has been displayed, it has been “liked” by 480 people, shared by 182 people (multiplying its reach at no charge to the advertiser), and has received 61 comments. Every one of those comments is from a man who confirms that he was born in September (usually adding a year from the 1950’s or 1960’s) and wants one of the shirts.

Is the fact that I was shown this advertising a coincidence? No way! It is custom-tailored to my identity. If I went to the order page and modified the URL, I could display any of a number of t-shirt designs based upon:

• The name of the performer.
• The birth month.
• Whether I was a man or a woman.

Here is an example:

To make the ad even more effective, the ordering page includes a countdown clock to create a false sense of urgency:

Depending upon how you view it, being presented these ads is either a brilliant use of Facebook’s marketing potential or an egregious violation of the personal privacy of Facebook users. In this case, I was being shown advertising that was based upon the disclosure of my gender, age, month of birth, and taste in music … all information that I had either voluntarily or unwittingly published on Facebook for either my friends or the world to see.

Yesterday, I was presented with another variation of the ad, based upon the fact that I drive a Jaguar … another fact that I had disclosed on Facebook. Now, I can also order a coffee mug! I am sure that I could modify the URL on the ordering page to change the design to show the name and logo of just about any car company. (On a side note, I have to wonder if these performers and companies are being paid royalties by the t-shirt company for use of their trademarks.)

You may think that this is all innocent, fun, and the price we pay for the otherwise free use of social media apps like Facebook, but there is more involved. I don’t know how many times I have seen friends on Facebook post a complete set of answers to 50 personal questions such as the name of their elementary school, their first phone number, name of their eldest sibling, and so forth. Whenever I see this being treated as a harmless and fun exercise, I cannot help but ask myself, “Are you insane?” If any of these questions and answers seems familiar, it is because they are among the same ones that are used as security tests on your online banking or an e-commerce site when you reset a password. Yes, the name of your first pet can lead to the theft of your identity!

You may have seen the recent news about the “Google Docs” phishing scam that proliferated in e-mails on May 4, 2017, said to be the most effective e-mail worm since the “I Love You” virus that caused havoc back in 2000. The scam was effective because it looked legitimate (it is so easy to copy the appearance of a legitimate website!), came from somebody you knew (rather than some random name chosen by a hacker in Belarus), and was spread through the type of shared online document that we have come to accept as routine. Even cautious recipients who would never open an e-mail attachment from a stranger thought that it was safe to download the same sort of document that appeared to have been shared via a cloud service by a known sender. All of these scams, whether relatively harmless or downright nefarious, play upon the human willingness to trust those with access to our personal information.

At the moment, leading into Mother’s Day 2017, there are several gift card scams that are proliferating on Facebook almost faster than they can be identified and taken down. One purports to offer a $50.00 coupon for use at Lowe’s home improvement stores in exchange for taking a short survey, in which you will be disclosing a wealth of personal information. Another purports to offer a $75.00 coupon to Bed Bath & Beyond, the same sort of scam that attempts to gather your personal information for exploitation later.

As I have said in the title of this article, it is never too late to start guarding your privacy. In fact, today is the best day to begin!
