Janitor

From SA Mafia Wiki

A Janitor is a Mafia role. Typically, if the Mafia have a Janitor in their team, then the Mafia can perform the nightkill as usual, and then have the Janitor "clean up the scene," thus causing the Town to lack the killed player's cardflip. The player will simply be flipped as "???" or ":iiam:" or some variation thereof.

In some versions, the Janitor must perform the nightkill themselves; their cleaning up is not a separate night action.

Occasionally the Mafia will be given the cardflip privately, allowing them to potentially use the information as a fakeclaim, or to simply just have information the Town does not.
