I'm so glad I checked this forum! I, too, have a hateful "stalker" who just changed her store name and continued her haunting under another name. I want to retaliate and blow up HER wall, but two wrongs don't...well, you know the rest!
I'm disabled, and spend A LOT of time AND money playing Fashion Story (in addition to Bakery Story, and Dragon Story on two devices!) from my bed, and agree, there should be a blocking feature on Fashion story too, as I've only experienced a problem on THIS game. I don't know what else to do other than post on my own wall warning my neighbors to beware of her two names, yet fear her retaliation in slamming all of them as well! What a catch 22! Grrrr.....
