Limnoria/plugins/Karma/README.md

This will increase or decrease karma for the item.

If config plugins.karma.allowUnaddressedKarma is set to True (default since 2014.05.07), saying boats++ will give 1 karma to boats, and ships-- will subtract 1 karma from ships.

However, if you use this in a sentence, like That deserves a ++. Kevin++, 1 karma will be added to That deserves a ++. Kevin, so you should only add or subtract karma in a line that doesn’t have anything else in it.

If config plugins.karma.allowUnaddressedKarma is set to False, you must address the bot with nick or prefix to add or subtract karma.
