I'm sure this exact same thing happens every few months: a few people lose whistle status and cause a HUGE fuss about it. I've seen it time and time again in this forum, and TBH it's getting kinda boring.
This thread will accomplish nothing. If all you care about is your whistle status, then just go back to flagging reviews to get your whistle back up, and confirm what is and isn't OK with review mods before you flag if you're unsure.
I had something similar happen to me when I first started using the whistle system. I was on a Gold whistle, then flagged a load of reviews of a spam alt which SHOULD have been cleared without any points (positive or negative), and the account put in line for deletion. Because it was the first time that kinda thing had happened, a review mod made a mistake and gave out negative points to all who flagged the reviews, so I went down from Gold to Normal. I didn't spend my time bitching at every available opportunity though, I just kept on flagging and after about 2-3 weeks I got my Gold whistle back.
You shouldn't be so quick to place the blame on review mods for this kinda thing. For all you know, you could have wrongly flagged stuff ages ago that only just came up for moderation, (reviews OR movies), and it's only now that you're losing points for it. I DUNNO. I don't care either, I'm just trying to help you see that IT IS SOMETIMES YOUR OWN FAULT.
I know people don't like to hear that, and if you're one of those people, don't bitch at me because of it. That's life. Sometimes you fuck up, sometimes other people fuck up, but at the end of the day the best course of action is to stop whining and get on with it. After all, it's only a picture of a whistle on the internet. If you really wanted to help the site out it shouldn't matter so much to you.
