Ephemeral Apps

Many adults have heard of Snapchat and Instagram Stories, but what about Live.ly, a rising live-streaming app with a large teenage audience? All three work like a disappearing magic act. You send photos, texts and videos, and poof.

Chances are, your teenager is using Snapchat: 75 percent of teens use the app, according to an Associated Press-NORC Center for Public Affairs Research survey in April. In late June, Snapchat introduced Snap Map, a mapping feature that will share your location with a charming “Actionmoji” every single time you open the app. (Set it to Ghost Mode to turn this function off.)

Instagram Impostor Accounts

In early May, Dawn Dunscombe, who lives in a small New Jersey suburb, learned that an Instagram account with the handle “I Have A Crush.1” was devised to impersonate her 10-year-old daughter.

Ms. Dunscombe’s daughter does not have an Instagram account. Yet the fake account was filled with posts, including claims that her daughter had a crush on a boy in her class. It wasn’t the outed crush that upset Ms. Dunscombe — the tormenting song that someone is “Sitting in a tree, k-i-s-s-i-n-g,” is playground standard — it was that the fake account was created in her daughter’s name so easily and with the purpose of damaging her young daughter’s reputation.

Profanities and rudeness littered the account, which is what gave it away. “A classmate told my daughter, ‘I knew it couldn’t be you because you don’t curse and you don’t talk rude like that to people,’” Ms. Dunscombe said.

By the time Ms. Dunscombe tracked down the account, it had been shut down. The school investigated. No one confessed. Ms. Dunscombe contacted Instagram multiple times and got a generic message. The situation was handled. Account closed.

Management Strategies

Getting rid of an app is like playing whack-a-mole — particularly because many young people maintain multiple accounts with varying levels of secrecy.

“This arena in social media that we’re working in changes so quickly,” said Robert Appleton, the New York State Internet Crimes Against Children task force commander. “The kids don’t want the parents to discover what they’re using, so every time a new app comes out, they’re switching.”

And behavior, not apps that enable it, is the problem, said Elizabeth Englander a psychology professor at Bridgewater State University and director of the Massachusetts Aggression Reduction Center.

“I could give you a list of things that kids tell us they do to each other,” Ms. Englander said. “But the more interesting question is: ‘Why are we seeing misuse of apps and technology perhaps among teenagers who wouldn’t engage in those behaviors in person?’”

“Monitoring and surveillance control aren’t always the most effective way,” she said. “It’s really best to have a human way of monitoring the situation.
