Fair enough. I've got to say, I have a lot of questions I'd like to put to the OP but... nevermind- not my problem ;)
Slight Edit: I'm thinking if the OP thinks that checking IP addresses will be enough to stop fake reviews then... maybe not? I mean, we've had some weird reviews from some interesting people but never anyone just saying "great game" or "fantastic game" on the only game they've ever reviewed! Ok, I'll stop now, I promise ;)
