Anton was found guilty in October 2021 of insulting a government official. The charges stemmed from a comment he left under a post on the social media account of political prisoner Pyotr Zinevich, referring to the acting commander of the Minsk OMON unit, Warrant Officer Yevgeny Savich.
Anton had approximately eight months of house arrest remaining. However, due to alleged violations of the terms of his sentence, on April 11, 2023, his sentence was increased and he was sentenced to four months in a penal colony. He was remanded in custody after the trial.
He was released in the summer of 2023, having fully served his sentence.
