Twitter is now adding a controversial 'hacked materials' warning label to tweets

“These materials may have been obtained through hacking,” reads the disclaimer affixed to a tweet linking to a story from independent news outlet, The Grayzone.

The tweet was originally posted on Feb. 20. However, three days later, users began to notice the label added to The Grayzone’s tweet. (It is not yet clear when exactly the label appeared.) Furthermore, readers discovered that an extra step was added when trying to retweet posts linking to The Grayzone’s story: A pop-up appeared reiterating the warning label and asking users to “help keep Twitter a place for reliable info.”

The Grayzone’s story sources recently hacked and leaked documents which allegedly show that the BBC and Reuters participated in a program created by the UK government to “weaken Russia’s state influence.”
