Might not work in an experienced lobby but what about pretending to ask all the mafia what they are claiming, except you are Jailor Jailing a random person. So like, if the random person responds “TI” or smth along those lines, you basically just outted a Mafia member cuz they thought they were talking in the Mafia Chat when in reality they were talking to the Jailor.
Easy Ques: Jailor’s name in Jail is “Jailor”, and there are bars with a message that says you are hauled to jail.
My recommendation: Name yourself Jailor every game and have the fake mafia message ready in CAPS when you roll Jailor, instantly post as soon as the night begins
