Because people tend to lie when they can hide behind the anonymity of the internet. Sometimes it's just to get extra attention (that they presumably don't get in their offline lives), but usually it's just to rile people up.
This.
P.S. if someone actually has a real copy, all they need to post it online is a 3rd party. Like a friend, or a trusted internet buddy. No chain back to the original copy. Thus no legal actions. No risk.
Right no risk to the person. Just there close friends or someone they know. Thats nice. Everyone just makes it sound so easy. Would I like to play early sure. But I understand the position such a choice puts someone in. I've had early copies of things and the such and decide against posting it for the world. Most people aren't even that grateful to who puts there neck on the line for there impatient need for entertainment. Im sure some are but most dont care where it comes from just that they get it. So its unfair if you fall into that category which most do... to look down on someone for saying somthing that they have no real need to prove.
I don't think anyone here expects anyone who "has" the game to leak it. I know I wouldn't leak it if I had it (well I wouldn't publically admit it to it anyway). But posting a picture doesn't carry the same risk. And for a reviewer (which samred has implied he is w/ the NDA comment) a picture would actually be allowed - no legal risk whatsoever. Even for someone who got it through unofficial means, the picture doesn't really carry a risk as long as there's no personally identifying info in the pic (real name, address, last 4 of CC, etc..)
