Social media has become such a part of our lives, millions and millions of us use it every day, with a recent survey finding 90 percent of teens rely on it to stay in touch.
But a growing number of those kids are migrating to more obscure sites that may offer privacy for parents prying eyes.
Sites like Tumblr offer complete anonymity for users to post their thoughts, pictures and videos, with no filters to prevent easy access to very explicit content.
Psychotherapist Mary Jo Rapini says it can be a dangerous place for teens who are still learning live within appropriate boundaries.
"With social media, all those boundaries have been expanded," says Rapini, "There really are few limits, so it's harder for parents to corral their children in and say 'You can go this far, but not that far."
Rapini reminds parents they need to be engaged with their children and set boundaries, with clear repercussions if those lines are crossed.
