I disagree. Not everyone has an easy relationship with computers and technology. These sort of acts have the potential to seriously disturb some people that have been forced to use the Internet to get by in modern life, but do not have a full grasp of what it is and how it works.
How would you feel if this was done to your Grandmother?
Pretty much same way as if someone would peep at my Grandmother disturbing her and left something disturbing on her doorstep or teased her any other way.
Actually I'd feel bit better because in computer scenario I would know what to do help her.
