Update: After Rob Kardashian's profile was taken down from Instagram Wednesday afternoon, he re-posted a series of posts and nude images on Twitter.

The strange, sad saga of Rob Kardashian and Blac Chyna has officially stooped to a new low.

In a string of now-deleted Instagram posts, Kardashian launched a public, wildly profane attack on his ex-fiancée, marking a shocking new development in their relationship. The couple's unlikely pairing was the basis of their Rob & Chyna E! realityshow, before things went south following the birth of their daughter Dream last year.

First, Kardashian posted and deleted nude pictures allegedly showing Chyna, claiming that she sent him a video of her kissing another man, which he also posted on Instagram. Over the course of 10+ subsequent posts, Kardashian accused Chyna of getting cosmetic surgery on his dime then disappearing after their daughter Dream was born, in addition to staging paparazzi shoots, repeatedly cheating on him and sending him videos of her affairs.

He also dragged his half-sister Kylie Jenner into the mix, who previously dated rapper Tyga, the father of one of Chyna's children. "My daughter is the best thing that happened to me and she will know that Chyna did this out of spite not love cuz she mad my little sister took her baby daddy," Kardashian wrote.

Many Twitter users called Rob's attacks on Chyna revenge porn, pointing out that posting naked photos without her consent could constitute a crime, particularly in their home state of California which passed a revenge porn bill in 2013.

Nevertheless, another corner of Twitter ate up the drama, celebrating Rob "exposing" his ex by posting reaction GIFs.

One thing that Twitter could agree upon was the situation's tragic ramifications for their daughter, with "Poor Dream" becoming a trending topic along with Rob, Chyna, Kylie and Tyga's names.
