Rob Kardashian said Instagram shut down his page on Wednesday, following his flurry of posts attacking his former fiancée. Kardashian then transferred his tirade to Twitter, accusing fellow reality star Blac Chyna of infidelity, promiscuity and drug use. Both were top trending topics worldwide on Twitter. Earlier in the day, Rob posted explicit photos of Chyna on Instagram. She responded on Snapchat with a claim that he had beaten her. Kardashian and Chyna announced their engagement in April of 2016. The couple split up a month later.
