Don't be fooled into believing it has any validity - it doesn't. People who bully are adept at creating conflict between those who would otherwise pool negative information about them. The method of creating conflict is provocation which bullies delight in because they know they can always coerce at least one person to respond in a manner which can then be distorted and used to further flame and inflame people. And so it goes on. The bully then sits back and gains gratification from seeing others engage in destructive behaviour towards each other.
Most serial bullies are also serial attention-seekers.
The best way to treat bullies is to refuse to respond and to refuse to engage them - which they really hate. In other words, do not reply to their postings, and on forums carry on posting without reference to their postings as if they didn't exist. In other words, treat nobodies as nobodies. The anger of a serial bully is especially apparent when they come across someone who can see through them to espy the weak, inadequate, immature, dysfunctional aggressive individual behind the mask. The objectives of bullies are Power, Control, Domination, Subjugation.
