The debate in the meme mafia has gotten me thinking about modkills. To me, it seems like they are actually beneficial to town. Even if the player turns up town, the town still knows his role without wasting a lynch or vig ability. This leaves town open to use their abilities on the scum and to use the information that is gathered from the modkill, to give them a better chance to catch them.
The easiest way to fix this (besides just never have anyone deadbeat) would be to not reveal the role of the modkilled player. However this also comes with its own bias. Now, the mafia are getting free kills and are getting the bonus of keeping the town in the dark.
Maybe I'm wrong in my thinking though. Anyway, how should modkills (assuming you have to make one) be handled so that neither side gets a large advantage?
