With the new role breaking rules, would an inno breaking the tester for no reason, (or any reason), fall under this? What would the punishment be? "Role Breaking is playing your assigned role (Innocent/Traitor/Detective) against how it should be played, often in a way that harms your own team and/or assists the enemy team." It harms your team, and assists the enemy.
Apparently the rules say a little further down that this scenario is not role-breaking, so this can be closed.
Yeah it's essentially covered in the Extended Rules: Breaking testers and health stations as an innocent/detective is NOT considered role-breaking. However, it can be considered Game Throwing if the intention was proven as such (i.e. an innocent/detective breaking the tester to let his Traitor partner avoid having to test)
