NSFW Content that contains nudity, pornography, or profanity, which a reasonable viewer may not want to be seen accessing in a public or formal setting such as in a workplace should be tagged as NSFW. This tag can be applied to individual pieces of content or to entire communities.

I like this sub, it’s really interesting to look at, but in certain settings some of these picturs can be inappropriate. So no, it might not be nessesary to mark everything NSFW but it would be nice to get a warning, if you are just scrolling through your reddit feed.

If you mark the community NSFW, I think that visiting the community, you will see everything normally, but that if you are scrolling through your feed, things from this page will be marked NSFW. Just a thought.
