We have filters set to try and catch objectionable content (e.g., potty words, etc.) but they're not foolproof. So we also rely on users to monitor each other and Flag objectionable content. When that happens, it will appear in your Flagged section.
You have two options at that point:
1) Ignore the flag - - If after reviewing the post (photo and comments), you see no reason for the Flag, select Ignore.
2) Remove - - If after reviewing the post (photo and comments), you do find something objectionable or inappropriate, you can remove it from the app by selecting the Remove icon.
