Ethics?: Trusting the Mod

[Norinel]

From Ethics: Setup Change In-game:

Also, lying as the mod when it comes to setup-reveal is a no-no, too. Public information from the mod has to be trustable at all times - whether that be vote-counts or death reveals. For example, I'm of the opinion that death-millers are

not

a legitimate game device.

And while I don't want to start off with an essay, I'm curious where the line is drawn by people as mods, where people as players expect the line to be drawn, and if/how the line winds up between "X is dead, he was scum" when X was town and "You are a cop, each night choose one player and I will tell you their alignment" to a nonsane cop.
