Mark is an entrepreneur and IT specialist and one of the most active authors of the Russian-language Wikipedia: since 2008, he has made more than 200,000 edits to its articles.
In March 2022, the anonymous Russian Telegram channel "Mrakoborets" accused Mark of spreading "fakes": he was one of the editors of the article on the invasion of Ukraine. Soon afterwards, he was detained by GUBOPiK, and the agency's Telegram channel posted Mark's photo with a caption saying that he "spreads fake anti-Russian materials". Mark was sentenced to 15 days of administrative arrest for disobedience during the detention, but he was not released after the arrest.
In June 2022, Mark was found guilty in a criminal case initiated under the article "Organization and preparation of actions grossly violating public order, or active participation in them" and sentenced to restricted freedom without referral to an open-type correctional facility. The court moved Minsktrans's claim for damages for "blocking" roads to separate civil proceedings.
