Social networks can have a positive impact on safety, such -providing a way of contacting others in distress -telling others that you're ok, for example during an earthquake -going around media censonship -sharing with the world stories of systematic abuse -sharing the information about human rights
But they can also have a negative impact on privacy: -a lot of data is published without the persons knowledge (pictures) -you don't have control over your own pictures published on others' profile -people can stalk you -people can find out about your past
