The rejection statement that comes up when abuse is flagged up is badly worded, but usually isn’t about the text. It most often is about using a photo that can be found on a third party site or for misplacing the pin for the nomination.

Often staff will respond directly to posts here, if you do not want to share with the rest of us.
