I don't shoot editorial but had some when I was in Seoul during the protest of the president. Ignoring the lateness and potential devalue of it, all of them were rejected and I'm not completely sure why:

Description: Protestors left thousands of sticky notes on the police buses during the Seoul protest of Park Geun-hye
Reason: Unacceptable Editorial Caption -- Caption is either missing factual who, what, when and where information, is too vague, contains inaccuracies or is not relevant to the subject matter.

Do I have to actually mention the date - it's in the photo exif? Most of the photos are of crowd/etc. but there was even one of a statue, with nobody in it

Description: A statue representing President Park Geun-hye during the protests in Seoul
Reason: Unacceptable Editorial Caption -- Caption is either missing factual who, what, when and where information, is too vague, contains inaccuracies or is not relevant to the subject matter.

City - Circa Date:
