Used to be right in "The Right Call (3.18) that the manager is not responsible.
By the way, I'm not a big believer that managers control the conduct of their player's parents/fans.
If you want to ask the manager to talk to the individual fine, it might work, but if it doesn't you can't blame the manager for the parent/fan being a jerk.
Was in the 2015 version.
Not mentioned in 2017.
