Snitching, or reporting neighbours, colleagues and even strangers to the authorities, was common in Russia's Soviet era. Now, as the government cracks down on critics of the Ukraine war, people with personal grudges and political ideals are denouncing others once again.
"I was taught how to snitch by my grandfather who was a snitch himself," claims a woman who goes by the name of Anna Korobkova. She says she lives in a large Russian city but refuses to say which one.
But she does say her grandfather was an anonymous informant for the Soviet secret police during Stalin's reign, when denunciations were part of everyday life, and she's following in his footsteps. Now, she is reporting anyone she thinks is a critic of the war in Ukraine.
Korobkova claims to have written 1,397 denunciations since Russia's full-scale invasion of Ukraine. She says people have been fined, fired and labelled as foreign agents because of her denunciations.
