Stanislav was convicted of "threatening to kill" RT employee Konstantin Pridybaylo and "inciting ethnic hatred and discord" against Russians. The charges stemmed from his phone call on September 14, 2020, to Pridybaylo at a number published in the "Black Book of Belarus" and the threat he made. He also made statements on internet portals, including the phrase "a good Muscovite is a dead Muscovite."
During the trial, it was reported that Pridybaylo was temporarily transferred to the Russian embassy in Minsk for safety reasons; he attended the trial only on the day of the closing arguments and filed a civil lawsuit for "moral suffering."
In November 2022, Stanislav's prison regime was tightened, and he was transferred from an open-type correctional facility to a penal colony. According to human rights activists, his health, including his vision, deteriorated sharply in prison; doctors diagnosed diabetic retinopathy, treatment for which was interrupted after his transfer to the penal colony.
In May 2024, he was released, having fully served his sentence imposed by the court.
