Last week, Adam Grandmaison—aka Adam22, the founder of the influential hip-hop podcast and video series No Jumper—took to Twitter to issue a blanket denial that he had ever sexually or physically assaulted any women. His statement came after anonymous allegations of sexual misconduct and physical abuse had been circulating on the social-media platform. “I’ve done plenty of stupid shit in my life. But I’ve never raped or hit a woman,” Grandmaison tweeted.

The accusations drew more scrutiny after Grandmaison announced he was partnering with Atlantic Records to form No Jumper Records, solidifying his status as what Rolling Stone called “underground hip-hop’s major tastemaker.” No Jumper, which has more than 1 million YouTube subscribers, helped launch XXXTentacion, Tekashi69, and Lil Yachty. The New York Times called it “The Paris Review of the face-tattoo set.”

Pitchfork has now spoken to two women who gave their accounts of alleged sexual assault and other misconduct by Grandmaison. He declined to comment for this story at the request of his lawyer. An Atlantic Records spokesperson told Pitchfork, “We take any allegations of this nature very seriously and we are looking into them.”

The first of the two women commented to Pitchfork under the pseudonym “Jane” due to fear of retaliation. In a series of emails and over the phone, she detailed her story, which began when she first met Grandmaison in 2005. They both posted on the same message board. One day they made plans to get together in Manhattan, and Jane ended up taking the subway with him back to his apartment in Queens, where he made advances.

“At first I was OK with it, but quickly became uncomfortable as it went further than I wanted to go,” Jane said. “I told him I wasn’t into it, but he didn’t stop and became pretty angry. Meanwhile, I’m not a big girl, I’m 5'4" and Adam is well over 6'0" and a pretty big guy. I was terrified and froze while he had sex with my basically lifeless body. I was too afraid to fight back in fear that he would hurt me, so I just laid there in terror. I just remember staring out the window and praying it would be over soon.”

She went on: “Eventually, he stopped. I changed and immediately left. I remember waiting in the subway, sobbing. Thinking I should have fought back, I should’ve gotten out of there. I felt guilty, violated, and scared.”

She said she confided in one person “who I thought I trusted” about the alleged assault, but did not go to the police or other authorities. “For reasons I still do not understand, he told Adam,” Jane said. “Adam immediately took to the public forum we were both members of and plastered my supposed ‘lie’ all over it.”

She was “mortified and humiliated,” she said. “I never mentioned the event to anyone again after that in fear of being called a liar or, worse, blamed for what happened. I didn’t feel safe telling anyone my story and just wanted to erase it.”

Several years later, in December 2009, Grandmaison wrote a blog post titled “The Time a Girl Accused Me of Rape,” which Pitchfork has viewed through Archive.org. He included photos of Jane as well as her first name. He also discussed confronting her on the message board about her account of the situation and described, in graphic terms, having sexual intercourse with her, which he maintained was consensual.

“She was letting me touch her all over and was making out with me the whole time, but she didn’t seem like she was really enjoying it all that much,” Grandmaison wrote about Jane in the 1,800-word post. “How much a woman enjoys sexual activity is usually not highly correlated to how much fun I’m having though, so I didn’t give it much thought.”
