Maybe it sounds obvious, but oversharing on social media is a BAD idea.
Remember the woman who posted a photo of a “creep” to Facebook that she thought was taking photos of her kids. He was actually taking a selfie with Darth Vader. Sadly, she’d already done the damage with her Facebook-shaming before the man could explain what he was really up to.
Once it’s out there on the internet it’s hard to take it back.
