Hated

From WoWWiki

hated ⇒ hostile

This is the lowest Reputation Level possible. This is the level below Hostile. Any player who comes close to anyone of this faction will be attacked on sight.

For example, players start off with the Brood of Nozdormu, Netherwing and Syndicate factions at hated. Both factions, however, start off at 0/36000, the lowest reputation possible in the game.
