A friend pointed out this petition on Change.org aimed at Amazon over the randomness and vagueness of their review removals. I'm not sure it will do any good whatsoever, but signing made me feel a little better.

So far no more of my reviews of vanished. Grudging is up to six. It should have been closer to ten. It's so hard to get reviews that any number disappearing is like a blow. I wrote about how discouraged I felt here. But I appreciate all the support I've gotten, and knowing this has happened to many more authors makes me feel less alone. Hang in there everyone!
