A content warning tag is similar to a spoiler tag, but you can fill out the warning yourself. So you could type something like "movie ending spoiler" or on Mastodon you'll see considerate triggers like "TW: suicide" for various trigger warnings.
Which the ability for that makes more sense then having multiple individual tags. Also ActivityPub supports it already anyways, and it works nicely on Mastodon
Cool, thanks. There was no disingenuousness in my query, just lack of info combined with apathy to go make yet another mastodon account I will likelt never revisit, for info gathering.
Basically when you add a content warning on Masto it'll just display that content warning in people's feeds but hide the actual content, unless they choose to click and expand. Blurs any attached images too. So you sort of know what you're in for if something is marked "CW: pet loss" for example, and can choose whether that's something you want to look at.
I think there's a setting somewhere to automatically expand CW posts if you're not fussed about things like that, but it's helpful for people who do have a common trigger.
