Unless you are actively monitoring your child's apps, you are not getting a complete picture of who they're talking to, says Jefferson County District Attorney Investigator Mike Harris.
Searching for other users based on proximity is the specialty of this social networking app that also includes chatting features. In fact, the location data was once a problem in one of Harris' investigations.
Bragging that it is the "best place to express yourself online," Whisper is an anonymous social networking tool. "It is anonymous," Harris explains. "Anything anonymous spells trouble for kids and those who look to prey on kids."
A ghost is the logo for this social network, representing the ephemeral nature of the messages it sends. The messages or photos disappear a few seconds after being opened. Like Kik, Harris warns this could be used to hide inappropriate messages.
Boasting 100 million users, Kik is an instant messenger with a built in mobile web browser. Harris warns that this is one of several options children could use to hide text messages from their parents.
Advertising that users can "post anything," Tumblr is a blogging service specifically suited to short posts and big images.
Owned by Facebook and boasting over 150 million accounts, Instagram is specialized in photo editing and sharing. Time magazine recently reported on the trend of users sending after-sex selfies across this service.
Users of this network can ask other users questions, and can remain anonymous when doing so. "This is the worst app I have seen as law enforcement has difficulty identifying anyone as Latvia doesn't work with USA Law Enforcement," Harris said.
The reigning king of internet video, Google's YouTube app allows the sharing of all kinds of video. "If the settings aren't set for children, there is lots of inappropriate content certain aged children should not be exposed to," Harris said.
