Russian hacker Igor Blinnikov, known in Moscow as the man who uploaded pornography onto a huge video billboard, has been sentenced to 18 months behind bars.

The incident occurred in January 2010. Blinnikov, a 40-year-old shipyard fitter, claims he randomly chose the billboard, which measures 20 feet by 30 feet in size and overlooks a heavily trafficked tunnel on Moscow's Garden Ring Road, reports the BBC.

The AFP reports that Blinnikov's graphic video ran for about 10 minutes and snarled traffic as it played.

When police initially questioned Blinnikov, he called the incident as a "bad joke." After his sentencing, he told the BBC, "I expected a bit less."
