Unfriend friend.

Social networkers amass friends on networking sites to show off to friends the numbers. A lot of times people just point and click without really thinking if someone is worth befriending.

To find and make someone a friend is easy because of the global reach of the social sites.

Getting a friend and kicking out a friend are easy does it.

But what do you do when a friend starts shouting vitriolic attacks against you, posting, as if in blind items usually done by showbiz columnists?

One, you can also deliver punches and blows on line.  Two, you can keep silent. Three, you can send and then exchange private message. Four and if the attacks get worse, you can bring the person to court. 

Friends who prowl and attack on line are cyber bullies. Friends who choose to send private messages to point out issues are prim and proper cyber netizens.

People who get hurt because you didn't buy into their financial woes, or those who dip into existing trivial spats, or those who harass out of ignorance, envy, spite, malice, and pure evilness do not deserve your attention and time, anyway. Unfriending these viles is your best and sane option.

Like Count Dracula, cyber bullies will suck you dry.
