If you followed Rob Kardashian and Blac Chyna's on-again, off-again relationship on "Keeping Up With the Kardashians" and the short-lived reality show "Rob and Chyna," you'll know that they ended on bad terms.

It's clear that Kardashian is still bitter over their breakup back in February.

On July 5 in a series of Instagram posts, Kardashian accused Chyna of having weight loss surgery and appeared to post a video of his ex allegedly having sex with another man without her consent.

The 30-year-old appeared to publicly shame his ex — with whom he has a 7-month-old daughter, Dream — in a series of Instagram posts that he shared with his 9.4 million followers. Among the insulting posts, Kardashian shared a video body-shaming the 29-year-old reality star, who he claims had weight loss surgery after giving birth, as well as a series of explicit NSFW posts on his Instagram, including a video that Chyna allegedly sent him that he said showed her having sex with another man.

The first video that Kardashian posted was of Chyna in a hospital bed being taken to another room. Kardashian claims the video (the second post in the screenshot from his now-deleted Instagram below) shows her being whisked off to have weight loss surgery.

His full caption reads: 

Everyone wonders how Chyna lost all that weight after the baby and she lies to everyone but no I'm such a great Husband that on our anniversary I paid [$100,000] to do this surgery to get all everything fixed as much as they could. And then guess what she did after she was all healed when I was by her side the entire time. She left me and my baby which she had out of spite to get back at her other baby daddy. I can't believe [you] would disrespect me like this.

In the video, Chyna thanks her ex and he says he loves her. The content of the video, in which Kardashian is supportive, feels very much at odds with the body-shaming message he posted on Instagram.

In another now-deleted Instagram post, Kardashian wrote: "I had my daughter out of Love but this woman left the second I paid for her body surgery."

Kardashian didn't stop at publicly body-shaming Chyna.

In a now-deleted video, he shared a video of his ex-girlfriend that allegedly shows her having sex, as well as posting a photo of a man she allegedly slept with and several screenshots of iPhone notes that accuse her of cheating on him and doing drugs.

Things got messier as he continued to level allegations at Chyna about her past and even exchanged words with rapper TI.

Kardashian shamed Chyna for breastfeeding for four weeks "because she wanted to drink alcohol so bad." He wrote in another note that he has spent a lot of money supporting her, shelling out $250,000 for jewelry in one day.

One of the posts appears to show a text message exchange between the two of them, with what some people believe to be Chyna's number at the top. (You can see the exchange in the third on the top row of this screenshot of Kardashian's Instagram below.)

He later reposted a comment from the rapper TI, and responded by accusing him of paying Chyna to have a threesome with him and his ex Tiny Harris. Though the photo (and Kardashian's caption) has since been removed, she can see TI's response in the first post on the top row of the screenshot above.

At first, People reports that many of Kardashian's Instagram posts were being taken down, though it was unclear if they were deleted by the social media site or Kardashian himself.

After Kardashian's Instagram attack, Chyna responded on Snapchat and accused her ex-fiancé of domestic violence, according to People.

"Rob [you] did all this but [you] beat me up and try act [like] it never happen[ed]!!!!!"she wrote in a now-deleted Snapchat post. "[You] put hand on me I swear on god!!!! On my kids [I'm telling the truth,] but I'm supposed to be quiet because you're a Kardashian."

A second post, which was also deleted, read: "The light will come to the light."

Twitter users responded to Kardashian's insulting Instagrams as well, pointing out how "wrong" he was to post the explicit footage of his ex and how he may have broken the law by posting the reportedly nude images of Chyna without her consent.

Then Kardashian's Instagram account was abruptly deleted.

Later, it appeared that Kardashian had deleted his Instagram account and all of his posts had disappeared.

However, the reality star quickly took to Twitter to explain that his account had been shut down. 

Kardashian continued to blast Chyna with graphic images on his Twitter account instead. The nude photos of his ex-fiancé remained on his account for a full half an hour before they were removed.

He posted a series of tweets reiterating some of his earlier comments on Instagram.

Kardashian's social media attack on Chyna and the allegations that he beat her are incredibly disturbing.

While we don't know whether the accusations are true, such abuse — whether in private or public — is in no way acceptable. However badly someone has treated you in a relationship, posting body-shaming material and potential revenge porn is never okay.
