Azealia Banks
Azealia Banks is everyone's favorite person to hate. She had a rapping career that was actually pretty successful until she started fighting people on Twitter. At first, it was funny. Then, she started to play dirty and lost her fanbase completely.
Twitter Wars
She really did lose her career. She's been arrested for violent behavior, banned from Twitter for harassment, and lost all of her endorsements. No one in their right mind would work with someone who had real, personal beef with Lady Gaga, Iggy Azalea, Zayn Malik, Russell Crow, Elon Musk... etc, etc.
