ISIS supporters have threatened Twitter co-founder Jack Dorsey as well as company employees because the terrorist organization’s accounts are frequently deleted from the social network, reports Buzzfeed.

The post was uploaded to JustPaste, a site frequently used to disseminate ISIS propaganda, features an image of Dorsey with cross-hairs superimposed. It reads, “Your virtual war on us will cause a real war on you.

“You started this failed war. We told you from the beginning it’s not your war, but you didn’t get it and kept closing our accounts on Twitter, but we always come back.

The message goes on to criticize Twitter for closing ISIS-related account and makes an explicit death threat.

Twitter’s terms of service forbid users from posting “direct, specific threats of violence against others.” The company deletes posts that feature videos of the terrorist group’s violent acts and suspends its accounts as quickly as possible.

Twitter is taking the threat seriously. A spokesperson told TNW, “Our security team is investigating the veracity of these threats with relevant law enforcement officials.”
