I'm firmly in the "I don't use social media" camp and it really is a very bizarre thing for a lot of people to wrap their heads around.

What makes it worse is that the same people who attempt to post them pictures also take personal offense at being asked to remove them typically so it just makes for a very uncomfortable situation so if there are tools to avoid it I can understand wanting them. People have a hard time grasping that what you put on the internet is there forever.
