Twitter gives all users access to the content warning feature it tested last year. The feature lets you obscure individual photos and videos behind warnings for nudity, violence, and “sensitive” content rather than adding a blanket warning to all multimedia tweets. It’s available on Twitter Android and iOS apps as well as its web client.
Users can put a content warning on posts by adding a photo or video, tapping to edit it, and then hitting a flag icon that will bring up the options listed above. Users can tag multiple warnings for an individual piece of media. They can add a warning to one image or video in a tweet but not another — although in the latter case, Twitter appears to place a single alert over both of them.
But members of other platforms have used them in more complex ways. The decentralized social network Mastodon lets users write freeform content warnings that can be applied to text or multimedia messages, working as an informal tagging system for posts. Twitter system remains limited by comparison, but it’s more versatile than its predecessor — and you could still hide spoilers behind it in a pinch.
