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.
I'm not much on PS3 anymore and no I didn't and probably never get a PS4, but I do play games on PC, my Steam ID is Veikkeli. Feel free to add me there if you miss me, sometimes I'm on Vita. Also follow me on Twitter: @Veikkeli and visit my website: http://veikrium.org/
