Valentin was found guilty of posting an image on a banned Telegram channel in June 2020, along with a caption that the state prosecutor claimed was offensive toward Lukashenko. During the trial, it emerged that a linguistic expert had assessed the caption inconsistently and found it not to be directly offensive to Lukashenko's honor and dignity. Despite this, Valentin was sentenced to imprisonment in a penal colony.
He was released in February 2023, having fully served his sentence.
