Players can right click and increase or decrease another player's reputation every three hours in game time. This has no in-game combat benefits or anything but will show up on scoreboard on hub and when you click on your character. It shows the popularity of the player and whether or not he's an asshat or not. Also, players with 30+ reputation will have golden text. Getting jailed or banned reduces reputation by 25.
A new character must wait three hours before being able to give reputation.
