The Nikon Cafe was created by Flew and Patrick Bramlett specifically as a place where they and their (expanding circle of) friends could discuss their photography without the noise and adversity that there is so much of in the DPR forums. By creating the Cafe, and starting out by inviting people who were expressing their frustration with the attitude on those forums, they built an atmosphere of support, learning and comraderie.
I have yet to visit any forum where the members care so much about keeping the experience positive. That isn't to say that DPR isn't a valuable resource - it is - but hanging out here is just better. It's usually best to leave DPR conversations there.
And yes, what Flew said is right. The security team here is pretty merciless as far as I can tell. People who come here to stir things up won't be allowed to do so.
