You may now add content warnings to individual tweets on Twitter
Twitter is making the content warning function, which it tested last year, available to all of its users. Instead than applying a blanket warning to all multimedia tweets, the functionality allows you to disguise particular photographs and videos behind warnings for nudity, violence, and “sensitive” content. It is accessible through Twitter’s Android and iOS mobile applications, as well as its web client.
Posts can be marked with a content warning by including a photo or video, touching to edit it, and then clicking the flag symbol, which will bring up the options indicated above. You can tag numerous warnings for a single piece of material, and you can add a warning to one image or video in a tweet but not another — although, in the latter situation, Twitter appears to place a single warning over both of the images or videos in the same tweet.
