They will definitely hurt her. In any type of industry or working/learning environment you're suppose to learn how to make connections. Starting feuds will not help further your career if you don't have enough friends. Look at Katy Perry for example, she has TONS of connections that she mentioned in an interview once. Even though other labels rejected her, she still kept contact with them. Now look at her, she's often getting nominated by her fellow peers each year at the Grammy's. Azealia needs to grow up now, she's not the same 19 year old girl we saw from 212. Time to act like a real adult now.
