Polish authorities last week arrested the alleged owner of pirate website KickassTorrents, or KAT, 30-year-old Artem Vauln of Kharkiv, Ukraine. Vaulin faces charges in the United States of conspiracy to commit criminal copyright infringement, criminal copyright infringement and conspiracy to commit money laundering. The U.S. entertainment industry lost more than a billion dollars in profits due to KAT's operations, according to a criminal complaint filed in a U.S. district court in Chicago.
