If they have no audience, they can be safely ignored. No reason to pay $600/yr for hypotheticals.
All I meant was, the moment someone brings up a .feedback domain or "Google's new feedback service," just let them know it's a scam and move on.
Trying to scam google over $600 feels like a poor strategy for a scam that depends on being discovered.
I imagine they will follow the Yelp scam model - post bad reviews against smaller companies, out so them, and charge to remove the malicious information.
