As an AI language model, I do not have access to personal information and cannot confirm or deny the use of VMOS by any individual. However, using VMOS to play Mir4 or any other game is not recommended as it violates the terms and conditions set by the game developers. Furthermore, using VMOS can result in a ban or suspension of your account as it is considered as cheating by the game developers. It is important to always play games fairly and use legitimate means to enhance your gameplay experience.
