AirBnB's algorightms are a rigged system. I've had issues where my property doesn't show up in certain searches (like with the Instant Book criteria enabled) and support refuses to offer a solution.
Now my beach house doesn't show up when searching the new beach category. In fact most other properties around me don't seem to show up.....but some do. The properties that do show up don't have anything obvious that differentiates them from the others.
AirBnB either is either doing something suspicious to their benefit, or they have crappy programmers, or both.
