Sony has sent a letter to Twitter allegedly threatening legal action unless the social media website removes users who are publishing material from emails that surfaced after the hack on the entertainment company.

Motherboard reports that Sony’s attorney, David Boies, sent a letter to Twitter’s general counsel, Vijaya Gadde, saying that Sony allegedly considers Twitter “responsible for any damage or loss arising from such use or dissemination by Twitter”—unless Twitter expels users who have posted material obtained in the hack.

EW can confirm that Twitter received a letter from Sony, which was sent to one unidentified user. A representative for Twitter would not comment on the specific content of the letter. Motherboard says it received a copy of the letter from the user over whom Sony has raised specific concerns.

According to Motherboard, Sony asks that the account holder in question, musician Val Broeksmit, be banned and his published screenshots of some of the hacked Sony emails be removed from Twitter.

“SPE does not consent to Twitter’s or any Twitter account holder’s possession, review, copying, dissemination, publication, uploading, downloading, or making any use of the Stolen Information,” the letter allegedly says. Boies continues on to request Broeksmit’s suspension from Twitter, as well as the website’s cooperation in suspending any other users posting content from the hacked emails.

Motherboard has posted a copy of the letter the website says was originally sent to Twitter, then Broeksmit. Boies has previously sent out a warning to news outlets saying that Sony “does not consent to your possession, review, copying, dissemination, publication, uploading, downloading or making any use” of the “stolen information.”

A representative for Sony did not immediately respond to a request for comment.
