Is this a grammar error?

[kipper_]

So why is it that authors are allowed creative liberty on a book but we as authors of the review are not allowed some creative liberties as well? Or at least not discounted the same points for a comma “error” as something more overt like a misspelling?

The rules and expectations are different for reviewers on OBC than the ones for authors. Their job is to create a literary work, while ours is to provide a review, based on the listed guidelines, in order to be compensated. The guidelines just so happen to have strict editing requirements. It’s an entirely different ballpark. If you think that you’ve been unfairly marked for a creative element that isn’t a true error, I highly recommend requesting a scorecard recheck (and an admin one, if it is subsequently disregarded). They’ve been quite generous and open to reconsideration when I’ve done so. At the end of the day though, our responsibilities are just different from the author’s.
