Back in the day, folks had to worry about their reputation in their local community. With the advent of social media, the community is now global and folks have to worry about their global reputation. Andy Greenberg reported in the Wired article, It Takes Just $1,000 to Track Someone’s Location With Mobile Ads:
When you consider the nagging privacy risks of online advertising, you may find comfort in the thought of a vast, abstract company like Pepsi or Nike viewing you as just one data point among millions. What, after all, do you have to hide from Pepsi? And why should that corporate megalith care about your secrets out of countless potential Pepsi drinkers? But an upcoming study has dissipated that delusion. It shows that ad-targeting can not only track you at the personal, individual level but also that it doesn’t take a corporation’s resources to seize upon that surveillance tool—just time, determination, and about a thousand dollars.
A team of security-focused researchers from the University of Washington has demonstrated just how deeply even someone with modest resources can exploit mobile advertising networks. An advertising-savvy spy, they’ve shown, can spend just a grand to track a target’s location with disturbing precision, learn details about them like their demographics and what apps they have installed on their phone, or correlate that information to make even more sensitive discoveries—say, that a certain twentysomething man has a gay dating app installed on his phone and lives at a certain address, that someone sitting next to the spy at a Starbucks took a certain route after leaving the coffee shop, or that a spy’s spouse has visited a particular friend’s home or business… https://www.wired.com/story/track-location-with-mobile-ads-1
See, https://drwilda.com/tag/privacy/ A University of Vermont study found that even if one does not have an account on either Facebook or Twitter your privacy is still at risk.
Science Daily reported in On Facebook and Twitter your privacy is at risk — even if you don’t have an account, study finds: Identity and actions can be predicted from friends — undermining idea of ‘individual choice’ on social media:
A new study shows that privacy on social media is like second-hand smoke. It’s controlled by the people around you.
Individual choice has long been considered a bedrock principle of online privacy. If you don’t want to be on Facebook, you can leave or not sign up in the first place. Then your behavior will be your own private business, right?
The new study presents powerful evidence that the answer to that question is no.
The team of scientists, from the University of Vermont and the University of Adelaide, gathered more than thirty million public posts on Twitter from 13,905 users. With this data, they showed that information within the Twitter messages from 8 or 9 of a person’s contacts make it possible to predict that person’s later tweets as accurately as if they were looking directly at that person’s own Twitter feed.
The new study also shows that if a person leaves a social media platform — or never joined — the online posts and words of their friends still provide about 95% of the “potential predictive accuracy,” the scientists write, of a person’s future activities — even without any of that person’s data.
Looked at from the other direction, when you sign up for Facebook or another social media platform” you think you’re giving up your information, but you’re giving up your friends’ information too!” says University of Vermont mathematician James Bagrow who led the new research.
The study was published January 21 in the journal Nature Human Behavior.
Privacy Matters
The research raises profound questions about the fundamental nature of privacy — and how, in a highly networked society, a person’s choices and identity are embedded in that network. The new study shows that, at least in theory, a company, government or other actor can accurately profile a person — think political party, favorite products, religious commitments — from their friends, even if they’ve never been on social media or delete their account.
“There’s no place to hide in a social network,” says Lewis Mitchell, a co-author on the new study who was a post-doctoral researcher at the University of Vermont and is now senior lecturer in applied mathematics at the University of Adelaide in Australia.

Summary:
New research shows that on social media, like Facebook, privacy can be at risk, even if a person doesn’t have an account. Scientists demonstrated that a person’s identity and actions can be predicted from their friend’s posts and writings online.

How information moves on social media platforms, like Facebook and Twitter, has become a powerful factor in protest movements, national elections, and the rise and fall of commercial brands. Along the way, people on these platforms reveal massive amounts of information about themselves—and their friends.
However, scientists have not known if there is a fundamental limit to how much predictability is contained within this tidal wave of data. In the new study, the scientists used their analysis of Twitter writings to show that there is a mathematical upper limit on how much predictive information a social network can hold—but that it makes little difference if the person being profiled, or whose behavior is being predicted, is on or off that network when their friends are on the network.
“You alone don’t control your privacy on social media platforms,” says UVM professor Jim Bagrow. “Your friends have a say too.”

Here is some great advice:
To quote Clint Eastwood in “Heartbreak Ridge,” “Shut your face, hippy.”
“How would your life be different if…You walked away from gossip and verbal defamation? Let today be the day…You speak only the good you know of other people and encourage others to do the same.”
Steve Maraboli, Life, the Truth, and Being Free“Gossip is just a tool to distract people who have nothing better to do from feeling jealous of those few of us still remaining with noble hearts.”
Anna Godbersen, Splendor“Rumor travels faster, but it don’t stay put as long as truth. ”
Will Rogers“Allow enemies their space to hate; they will destroy themselves in the process.”
