When playing online, you may register players you play with in your blacklist. By doing so, you will never encounter that player again. To do this while in the level, touch and hold the hero panel of the player you want to blacklist, press A or B, and select “Yes” to temporarily register them. Once you exit the level, you will be able to register them permanently.
You can register up to one hundred players on your blacklist. When you go over a hundred, the oldest entries will be overwritten.You cannot register a friend on your blacklist.
