I read a CNN article about a girl who was blackmailed to the point of suicide.
http://www.cnn.com/2012/10/12/world/americas/canada-teen-bullying/index.html?hpt=hp_c2My request is that you find the person who did the blackmailing. I am not asking you to break any laws to do it. This is a sad story, and i know that there are those here who have the ability to find this guy. Unless he's very good at hiding his online presence. Once you find him i suggest you report him to authorities. You can do this creatively, but again try and keep it legal.
Thanks.
