Appropriate use of digital media

Social media sites have made privacy increasingly hard to control, and it isn't always on purpose. I took a few pictures at a child's birthday party one time and posted them to Facebook. What I didn't know is that one of the conditions of my friend's foster child was that he wasn't supposed to have his picture end up online, and he was in the background of a couple of my pictures. I had no intention of doing anything wrong, and it goes to show how easy it is to cross privacy lines, even if you don't mean to. I was able to take them down quickly with apparently no harm done.
