Unfortunately, we can’t shut off the review feature, even though it’s not working properly. I’m pretty sure profile updates aren’t saving properly, either, so you may still be receiving anonymous reviews.
I know how frustrating this is, really. Everyone is doing all they can to resolve the situation, but if putting the archive online is only going to result in another attack, it’s not prudent. Once the site is properly hardened against this sort of attack, we can get back to being what we’re supposed to be—a fiction archive with readers and writers interacting happily.
