Whoever decided that "Hurt Feelings" has such a warped view on friendship, friendships work both ways. I don't want people on my list who are "Fake friends" that if I message to do something make up some generic excuse of being busy etc...
I've been removing anyone from my list that I wouldn't want to socialise with or do content with, just each time you open your list check the online ones and remove those who you don't want.
When your list has been narrowed down to who you consider friends it's time to try teleporting to the ones who have houses and if it won't let you then you've been removed by them so remove those people too.
