You can add a person to your block list if you no longer want to receive any comments, reviews or information relating to that person in LittleBigPlanet™ and LittleBigPlanet™ 2 or on LBP.me. Adding a person to your block list prevents that person interacting with you and you from interacting with that person in LittleBigPlanet™ and LittleBigPlanet™ 2 or on LBP.me
Please note! Blocking a person does not block them from sending you PlayStation®Network messages. If you no longer want to receive PlayStation®Network messages from a person, go to the PlayStation®3 XMB™ menu or PlayStation®Vita home screen. See PlayStation®3 or PS Vita User's Guide for details.
Don't let negativity and hate provoke you. Certain people don't have the capacity to think before they act. There's no discussing with no-brainers, so I simply suggest to not get caught up in their actions. It's not worth your time. Focus on developing your mind through positive thinking. Peace
