1:40 PM: Cardi B has now taken all her posts down from Instagram, too.
Cardi B may finally be tired of the constant invasion of privacy ... so she's gone private, on Twitter at least.
The hip-hop star just put her 3.06 million fans in the dark minutes after she tore into Azealia Banks for calling her a "Caricature of a black woman" last week.
In a lengthy post on her IG, Cardi refused to use Banks' name, but says "You busy trying to be a voice of reason and a representative for women of color when you can't even reason with yourself."
The "Bodak Yellow" rapper doesn't pull punches, telling Banks "Just because I mix a few words up or forget to use commas or misspel a few words doesn't make me illiterate and doesn't make me stupid. And because I laugh a little harder or talk a little louder doesn't make me a caricature!"
Finally, she says "I pray you find peace in your own heart and reason in your own mind! Pray for your own success before you pray for the downfall of others!"
It's unclear why Cardi decided to lock down her Twitter account after the clap back at Banks, but Cardi is done playing with the hip-hop troll.
