Well, that's at least some sort of improvement. There's
something provided as a reason for the assertion. Plus, it moves the ball from an assertion to an assumption.
I read the thread via the link provided. The original poster is
assuming that it is
one word (black) that prompted a warning "Metadata contains potentially objectionable or offensive language".
I read the entire thread and looked at the attached images. In addition to the keyword "black" other keywords included with the image were "danger", "public", "security", and "warning". If one were to make an assumption, it would be just as easy to assume that it was some
combination of the keywords and not just one. One could assume that it was combining the keywords "black, danger, public, security, warning" that triggered the warning before being compared to the image. One could assume whatever the imagination can conjure. Jumping may be good exercise for the body. Jumping to conclusions is a poor exercise for the mind.
From Shutterstock:
"Using appropriate language for keywords, descriptions, and captions""Creating the image is one thing. But, as with all stock photography, it’s equally important to label the image correctly, using the right keywords — especially if there are known biases or sensitivities associated with using the wrong keywords. It’s up to the photographer to be aware of this and make sure that he or she is using the appropriate language."
*Looking at guidelines from Shutterstock, it doesn't seem likely that simply using black as a keyword would trigger a rejection. It is, however, the one color that they recognize as both a color and ethnicity. Shutterstock encourages inclusion of ethnicity to aid buyer searches. "Some of our clients require model ethnicity information for legal reasons, so we encourage you to provide it where possible."

https://www.shutterstock.com/contributorsupport/articles/en_US/Why-was-my-content-rejected-for-Keywords?If you and the original poster on the Shutterstock contributor forum choose to assume something, that's up to you. Contacting Shutterstock for a fuller explanation of the initial rejection and their rules regarding usage of black as a keyword would be useful; but it might not be helpful for fanning the flames of internet outrage that result from assumptions racing to become conclusions.
