In this modern age of information, it's easier than ever to see what people think of a product, whether it be a new lawnmower, a console game, or an App Store app. But it's also easier than ever to try and tweak public opinion, and while there are many official avenues that will accept anonymous opinions, there aren't so many that will help you weed out the legit from the not-so-much.

App Store reviews have been controversial from the beginning -- while they can be helpful for buyers, you often have no idea just who's leaving comments or what their real agenda is. Njection, the makers of Nmobile (which we played with a while ago) are having a huge problem with what they're calling "sockpuppet" reviews on the App Store.

Someone (they believe this person is in cahoots with their competitor) is posting bad reviews on their app and trying to trash them and their product elsewhere (including in a comment here on TUAW). And unfortunately, as they say, they don't really have much recourse against this behavior -- they've appealed to Apple, who've replied that they'll leave comments up, unless they're offensive or extremely false. Apple's own guidelines for reviewing apps asks that the reviewers deal with apps on their own merit rather than attacking competitors, but that seems to be more of a recommendation than a firm rule.
