There are some memes which are marked as NSFW even though they aren't!

So true. The NSFW flag is so abused it’s become meaningless.

I agree. Also does a swear word count as NSFW because a mod put one of my posts as that because it said a swear word. Not a highly offensive one just a swear word

This was the post. I mean it’s a suggestive word but it was just a road name: imgflip.com/i/5kcsg5

Be better to see who marked it.

If you feel an image was falsely marked NSFW, get in contact with a stream moderator to have them review the situation. If that is not a viable option, then contact a Community Moderator (Green M) and ask them to review the situation.
