His name was cyxymu, more than likely targeted by the Kremlin, and you can follow his Twitter feed here.
He said he is a 34-year-old economics professor named Georgy (he wouldn’t give his last name), a married father of two. He said he is a refugee from Abkhazia, a region of Georgia that declared its independence in 1991 after the breakup of the Soviet Union, but is recognized by only a few of the world’s governments.
Georgy said he started a blog on the LiveJournal site to unite fellow refugees who would like Abkhazia to recognize Georgia’s authority over it. Last summer, Georgia and Russia went to war with each other, and Georgy started criticizing Russia — which recognized his homeland’s independence — online.
Worth reading… but just think about it: One man vs. one government, and it took out Twitter and brought Facebook, LiveJournal, and Blogger (attached to Google, mind you) to its knees.
