It is digital community where members interact, buy and sell goods, and build property worth real money. 250 of the in-world currency the Linden dollar can be converted to one US dollar at online currency exchanges, LindeX.
Recently, the virtual world began to face nasty troubles - crimes inside and outside the virtual world. The BBC reported that it had to close its doors for a short time on Sunday (19 Nov) after a worm attack called grey goo. The worm is presented as a golden ring inside the virtual world that replicates by user interaction slowing down the game servers.
The troubles do not stop here. A program that is designed to quickly copy characters, objects and buildings are eroding the value of people’s virtual property. A growing numbers of mafias and gangs in the virtual world are also seriously disrupting the law and order in the virtual world.
