@trinsec @WaysideLiege Yep. It's a banning offence actually ("NSFW without a content warning", see qoto.org/about/more#rules for context). I've marked this one as sensitive, but in future please make sure you post with the appropriate content tag.
If you'd like, you can set up your account so that it automatically marks any media sensitive when you post (Preferences > Preferences > Other > Always mark media as sensitive). This might help avoid trouble over NSFW images in future, in case you sometimes forget to tag them.
