Yeah. Where you can review things, there are always these morons who think they know everything best and therefore their own vote is the only one true vote that actually matters. They vote as low as possible or as high as possible to move the average score towards the score that particular moron would have voted the product. Say we have 5 people voted 5 on a product. Moron thinks that the product is only worth 4, but instead of voting 4, he votes 1 so the average score will be as close as 4 as possible.
Yuck.
