Probably an interesting business challenge. I could see a few options: 1. Add the ability to buy credits. Hurts the "community" aspect, but gets around that problem and acts as a revenue stream. 2. "Joe Smith is a new host! Camp at his place for zero credits in exchange for writing a review!" 3. Just accept that people in undesirable locations don't get to use the tool.
