A rogue mark is a reward item given to players who support Puzzle Pirates and Three Rings by purchasing doubloons, subscribing, or referring new players to the game. While similar to the shanghai points which they were created to replace, rogue marks are an individual reward: they are a stackable item that is stored in the "Miscellaneous" section of a pirate's booty panel, rather than a running total on a crew's info page. They can be traded between players just like any other item, but cannot be stored. Since they belong to individual pirates, deleting that pirate will cause any marks held to be lost. This is in contrast to the former shanghais, which were "owned" by crews and therefore not affected by pirate deletion.
