Block users from using messenger
I think there should be an option to block specific users from using the Messenger part of the app. The reason being if someone is being overly harsh or borderline bullyish you cannot stop it. Yes you can personally turn off notifications but as a commisioner you can't stop your overall users from seeing terrible things. Yes you could get rid of a user but we all know that at times during the year that is impossible. Case in point, I'm about to start the playoffs...I cannot delete the user in question as they made the playoffs. Yet the league is being bombarded with borderline psychotic rants from this person and I cannot stop it.
The commissioner already has the power to "mute" other managers.
