Azalea, 23, chastised "Internet kids" for targeting musicians online. She also blasted fighting between fans.
"Just remember while your all at home online cracking jokes about artists etc that Most of you have done NOTHING. NOTHING! With your lives," she wrote. "Don't flex someone else's achievements. So many of you Internet kids quote the feats of others as if they were your own."
"And just to clarify for anyone who didn't understand that last statement goes out to people who bully others...," she added.
Azalea also criticized infighting between fans of different artists, calling it "disgusting."
Don't be cruel to one another. And learn to understand how much work it takes to achieve anything in life.— IGGY AZALEA (@IGGYAZALEA) June 2, 2014
"Someone who's music you love doing great should never be an excuse to be awful to others. That's my point I suppose," Azalea said.
