For all of you that are hot on the trail of Mapspammers this post might help to speed things up :

Hack Google (Maps) URLs for Quick Searching

Basically, the multi-step process of going to Google [Maps], typing in an address, clicking submit, etc., can be avoided by just putting all your info directly into the URL. For example typing this works:
http://maps.google.com/maps?q=1683 Mass Ave, Cambridge, MA

So for example to find Cathy’s florist that she reported last week to Google Maps for Business Group you would simply type in the URL:

http://maps.google.com/maps?q=flowers with gifted elegance

To receive your secret decoder ring send along your recently found Mapspam.

(this would also work for those of you who just use Maps a lot and are not interested in joining the Columbo Mystery Squad)
