The labels, which the company has been testing since July, are an update from those Twitter used for election misinformation before and after the 2020 presidential contest.
But they can also allow social media platforms to sidestep the more difficult work of content moderation that is, deciding whether or not to remove posts, photos and videos that spread conspiracies and falsehoods.
The new designs added orange and red to the labels so they stand out more than the old version, which was blue and blended in with Twitter’s colour scheme.
Tweets with more serious misinformation for instance, a tweet claiming that vaccines cause autism will get a stronger label, with the word misleading and a red exclamation point.
