It is risky to have too many Hated townies in a game, since they could inadvertently put the scum one vote closer to dominating the town.
A non-Hated player who is told they are Hated is sometimes called Paranoid. They are called this because Fronz apparently felt it was necessary to make the word "paranoid" even more ambiguous.
An example of a well-known player is LITERALLY MAD IRL. What no disregard that last sentence!!
