Justpaste.it is a site that allows users to paste text (including HTML markup for formatting and display of images) and distribute the resulting link.

[4] Notable messages attributed to IS that have been pasted to JustPaste.it include a threat to Twitter employees who repeatedly shut down IS-linked accounts,[5] a list of names and addresses of American armed forces personnel,[6] and photos posted by an IS sympathizer that were used by bloggers at Bellingcat to identify the location of an IS training camp on the Euphrates river.

[3] Posting to JustPaste.it and Archive.org has been described as a response to Twitter's censorship of accounts, though "these anonymous posts eventually end up on Twitter", which suspended 20,000 accounts suspected of IS association in February 2015, but has been advised by the Brookings Project on U.S. Relations with the Islamic World to work out a "proactive strategy for finding terrorists" with the U.S.

[7] The site is owned and managed by Mariusz Żurawek, a 26-year-old Polish entrepreneur from Wroclaw, who holds a master's degree in informatics and econometrics.

"[3] According to Zurawek, "I’ve got a constant cooperation with the UK police, and if they found any illegal materials, they just send a take-down notice."
