There are certain industries and sectors that seem 'shadier' than others. When it comes to Google Maps and getting businesses listed in Google Maps/Places, certain industries take more aggressive approaches to ranking for certain queries.
Google's Vanessa said in a Google Places Help thread that the towing company industry is one of those verticals. She wanted to make sure that if you are in that vertical, you should know that. She said:
So I looked in to this a bit more. You definitely have a lot of editing history with the phone calls. Towing companies are a spammy vertical, so when an operator calls you on the phone to confirm the information, always be clear about old address, new address, give helpful information, don't be dodgy about it (I'm not saying you weren't helpful, I'm just saying this generally for anyone else who finds this thread and is in the same situation).
See that, don't be dodgy if you in are dodgy vertical!
