Flags/reports for bad keywords are reviewed by admin and approved or refused accordingly. Each time one of your images is flagged for irrelevant keywords, you will receive a comment. Please read it and compare reported keywords to the content of your image. Note that sometimes buyers will accidentally use the flag button instead of "Add to lightbox". If the keyword is striking relevant, most likely the flag was accidental and of course, it will not be approved. You can reply to mention that the user accidentally clicked the flag instead of saving the image.
