Why the Topic of Blackmail?

Because I see so many people practicing it online.  Yeah.  Particularly on Facebook.  Cousins, siblings, old friends do make references to regrets of friends, in their minds playfully, but in the context of a forum, a virtual room where we can imagine everyone hearing and seeing, well, it's not so playfully.  Not everyone can handle humiliation as well as the next guy.  But again, I see the joking on Facebook the most.  Some people make general and sweeping attacks in the hopes that the general attack will stick to the single individual or pair or trio who is the target.  See, it's just confusing.  I say stop Facebooking.  Take your self-ownership back and don't let people own you online.  The topic of blackmail is interesting precisely because it is so prevalent.  Some people prefer fewer friends because they don't want to make themselves vulnerable to someone else for fear that a detail could get used against them.  I really liked this video by a 19-year old on blackmail. It was thoughtful. She pointed out what horrible feelings of guilt can arise from acting on blackmail. I don't know. The people I've seen unleash blackmail on others have not been so kind and so sensitive as this young lady.
Andrea Weckerle makes some interesting points, but I can't see how she will have a following with this given the first amendment. People are somewhat free to say what they want. Her Twitter account is here.

This is another site that deals with blackmail.
