On May 13, 2021, the admins of the pro-Islamic State (ISIS) Rocket.Chat server published a post in English promoting the server, linking to several channels on the platform, and encouraging supporters to join. The post described the platform as "free from the censorship of the western media... Free from the deletion campaigns and fitnah [internal strife, and earthly temptations] on Telegram and social media and other sites. Find historical publications and media in our ever-growing archive channels. Share information safely with your brothers in Islam in channels and in private groups or conversations secured with sophisticated end-to-end encryption."
