This company routinely takes listings from classified websites and loads them into Google Base. This results in someone who uses Google Maps to click on a link for property at this address, and to be taken to the apartmenthunterz.com website.
They trick the Google Base system by falsely listing themselves as the broker and or agent for the property. At no time are they the agent for the property. This is in violation of California DRE code which prohibits more than 1 agent on a property and falsely claiming that you are in fact the agent.
The person who clicks on a Google Maps property and that ends up on ApartmentHunterz.com website is then told that the property in question is rented or no longer available. They are then shown homes by paying customers of ApartmentHunterz.com who have paid to have their apartments listed on their website.
So in summary, ApartmentHunterz.com is spamming Google Maps across thousands of addresses to syphon off traffic to their website which then pitches their own customers homes.
To achieve this, they must lie that they are the agent for the home (per Google Base/Maps legal department), and that they are the broker for the home which is in violation of California DRE (Department of Real Estate) law.
