Ignoring it and continuing on with your life isn't an option if you have to worry that next time you apply for a job someone is going to search your name and find that picture.

This guy wasn't posting these pictures annonymously, he was including personal and identifying information so that it would come up if you searched their name and even their facebook timeline. You should also look past the daughter in the story, what about the teacher who was fired on the spot when the photo was posted? Not only was she fired, but she would be unable to work in that field ever again. How could she possibly ignore what happened?
