The government has today said they are to introduce anti-trolling laws.
The proposed plans will make it easier for the victims of internet trolls to bring actions against either the ISP or the site owner where the comments were posted, or if the ISP or site owner discloses details of the troll the liability shifts from the site owner to the troll themselves.
The source of this is all over Sky News this morning :- http://news.sky.com/home/uk-news/article/16245551
To be honest its about time after being the victim of a troll myself, and if the law was changed I would almost certainly pursue a troll through the courts.
