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.

Be better to see who marked it.

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

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.
