Inappropriate use of Digital Media

I had some former students post inappropriate comments publicly on social media. They soon deleted them after they were "discovered", but not after everything in it's entirety was printed off and documented. They felt exposed and vulnerable after learning what they thought was a joke and "private" the whole world, and their parents, could now see what they wrote. I think they, and some friends, learned a lot about privacy (or lack thereof) on social media.
