They're hating on other celebrits for no reason (most of the time on Liam, Taylor and Selena). (And last tweet seems racist to me)
Calling Selena's voice "ebola of the music industry" which is not respectful to her and people that d*e because of ebola
I think that's the end 'cause Twitter won't let me look at their older tweets and this is just a few things they did but I think you all understand what's wrong with them and it's even worse that they stan Harry, someone who spread kindness
