i mean not claiming your role when lynches are not on you and mafia claims it in that scenario isn't really sub optimal play per se, I've let mafia claim my role just to get partner tells and then subsequently get their partner lynched that day and making the next day auto win. This guy has a history of trolling though so i can see why he would get a violation a lot easier
The mods aren't smart enough to give NotoriousPIG trolling violations despite his pattern of throwing being shown over the course of 3 consecutive games. They're even considering undoing one of his violations because they're not competent enough to preserve the integrity of games.
