Unfortunately, we're having an issue with spam reviews at the moment, which appears to be due to real people leaving them anonymously, thereby bypassing the captcha function we have in place to prevent spambots.
Authors already have the ability to delete anonymous reviews, so please use that function. There is no need to contact an admin to remove it for you. I've also turned off the ability to leave anon reviews temporarily.
If you start to get signed spam reviews - which happened on another site once we turned off anon reviews - please then report the user and we will lock the accounts and ban the ip address as well as deleting the reviews. Please report the user rather than the review, as that way we can find all reviews left, not just the ones on your story.
