And now he's on Twitter....
How long until he gets shut down there too?
Rob Kardashian has spent the better part of the day blasting his ex Blac Chyna on Instagram, but he could be looking at trouble.
He posted (and then deleted) nude photos of his ex-fiance, which under California law, is ILLEGAL.
The act is titled "revenge porn", better known as nonconsensual pornography.
Rob is now posting the photos on Twitter, due to Instagram shutting down his account.
WE ARE NOT POSTING THE PHOTOS.
