The watermark was on neither of the images submitted to Adobe. The monument/shrine is definitely not personal and private. It is located at the Manzanar National Historic Site in the Eastern Sierra (where Japanese prisoners were interred during WWII). Photography is allowed (and encouraged) everywhere throughout the site, even inside the museum. The characters translate to "soul consoling tower" which is how I titled the image.
Even if photography is encouraged, that does not mean that "commercial" photography is allowed. The moderation team is made up of many individuals. We cannot know the specific permissions allowed by all locations in the world therefor in many cases we are required to make a judgement call based on past experience with other images of a similar nature. In most cases, the moderators are told to err on the side of caution. I'm sure that is what happened here. My opinion is that both photos probably should have been rejected. This is clearly a structure designed and created by someone which makes it their intellectual property. It is clearly recognizable and does not appear to be more than 120 years old.
