Per your description; we have the same definition of trolls.

They're basically online gangs of punk assholes who sometimes make people's lives miserable. They can be relentless in their harassment, and occasionally take things too far. The original members of anonymous are a good example of a troll group, until some whitehats commandeered the name during the Arab spring.

They are not highly organized terrorists that have a political group agenda, or organized goal. Their threat is minimal, yet maddening to the victims. Not the type of threat the articles suggests.

The article aggrandized these punks for political reasons. This crap journalism will be cited in some internet antitrolling bill/law that will be used to silence investigative journalists, or forums that openly discuss contraversial subjects.

Please consider this further, as this is written to frighten Facebook using mother's into irrational opinions.
