I knew this thread would get more interesting (hits/replies) after someone was banned.
Let's break it all down, shall we. The reason why others weren't banned was because they weren't being deceptive. JapanGAF, for the most part, isn't deceptive, they just have to brag about games YOU can't play yet, and when you do, your mileage may vary.
All that we ask for industry folk to be upfront about where they work, what they do, and if they are to talk about their game, they need to disclaim themselves. That's only fair to other colleagues and the rest of community.
At the same time, they shouldn't expect everyone to kiss their ass when the game, accessory, or service is released. For reference sake, see Denis Dyack.
