I'm glad she had the courage to speak out about this matter.
I was really confused and dismayed when I heard the news, but I feel like her decision to delete her Twitter was so unprofessional of her, not that I expect her to be one, but she needs to take note that she is a radio act, a widely known star, so it's expected that things such as leaks and snippets occur.
Also, it's her or her team's responsibility to handle and secure the tracks if she really cared about it in the first place
It actually doesn't make any sense, imho. If you love your fans so much, why would you delete your Twitter? Just take a break and don't tweet. Her deleting caused mass hysteria within her small fan community and it was just ridiculous how she handled it. Don't sit there and be like, "I love you guys" when you shaded your entire fanbase and then paid them dust by ditching them.
But really, fans are the main culprits of leaks. She has to understand that leaking is part of the music business and it's why you have to really sit down and create a solid piece of work so that even if your music leaks, people will still want to buy it and support you.
