There is concern arising because of how much information about young people is shared online before they are able to consent to it, and without their control. From mothers sharing on Facebook about birthdays and playing to going into school and logging personal information into online databases, there is very little room, or choice, for privacy. This is ethically dangerous because a generation of adults has basically forced the generation under them to create a never-leaving digital footprint, which makes humiliation, discrimination, and identity theft much more possible in later years.
The article linked shares some overwhelming statistics which reveal just how scary it is to post your children online. For a child in today’s time, so many people know who he/she is, and only due to Facebook. This is both a good thing and a bad thing. Facebook Friends are not always “in real life” friends. Therefore, it can be scary that people my mother knew 20 years ago would recognize me from her facebook posts, especially since that time difference allows for people to have changed into someone dangerous, or someone I wouldn’t want to know who I am.
