why not? You have a low-mediocre career so disrespecting a known rapper gives you an edge making it seem as if "oh she's bold and brave enough to diss Lupe

?"
thusly making people youtube your shyt out of curiosity. I for one looked into a couple of her tracks after that Ebro interview
In her case she's just adding to a laundry list of folks she's "brave enough to diss". She's just a bridge burning idiot heading into 2015.
She's hit the point where when she goes in on someone else it's like "Don't she got something better to do?" Her social media presence ain't doing shyt for her music career because on Twitter she comes across as an emotionally bitter, hate everything in the world type of person that's constantly making headlines for going off on other artists instead of focusing on her music.
When your tweets make more headlines, and garner more hits, than the album you just released...you should prolly fall back from social media and work on pushing it out there more. Especially because she wants to be known for her music and creativity as opposed to what she does on social media. She need to quit bullshytting around and focus on her career because all she's done is piss off a lot of industry folks.
