L4sBotYou Can't Look at Porn on Any Reddit Third-Party App Now
DrMangoNot just porn! Since reddit only has one such tag you can apply to posts, many subreddits were using the NSFW tag for a wider variety of reasons such as spoilers, content which may contain unsettling material (aka “triggers”), and more!
To be fair, there's been a site wide spoiler tag for a few years now, but yeah before it was introduced people used NSFW for that if a community didn't allow actual NSFW stuff or whatever
