I've gotten some close calls as a result of my vocal hatred for the Kinect. But I felt it was worth the risk.
I still think the notion of getting banned, or even warned for hating on a hardware addon is as ridiculous as getting banned for hating on the Wii balance board, motion plus, or PS Eye.
It's funny though, now that the hype has died down, more people seem to agree with me on my hate :P
