Ask HN: What happened to Rolling.fm?

I was looking to take a break from Pandora, and realized that http://rolling.fm is gone. Disclaimer: turntable was not letting people in at the time.

This thing existed very recently, where did it go?? http://www.betabeat.com/2011/08/08/rolling-fm-yeah-we-copied...

I'm not sure but didn't they go around spamming people to join them telling them "someone" invited you?? Not sure if they got in trouble for that
