What I learned whilst watching this for 5 minutes, was that a lot of escort agencies use Google Maps and Google Earth to advertise.

I don't know how maps are classified, and whether data about businesses are adverts or just facts about places. But in the UK adverts have to be "legal, decent, honest and truthful, to the benefit of consumers, business and society".

As such, it opened up a whole new world of spam-fighting to me. Google must be scrubbing this dataset as quickly as others add stuff.
