Thanks again for bringing these cases to our attention. The issue involved was different from the ones that affected listings a few months ago. Like those, it’s now fixed.
As you all know, we’re working hard to clean up the spam on Maps, and to make it easier and easier for business owners to make sure their listings are accurate. Keep sending your reports to us at “Report an instance of a user spamming Google Maps business listings” found here: http://maps.google.com/support/bin/request.py?contact_type=contact_policy
The form (visible below) will hopefully encourage more active and detailed reporting of Mapspam to Google. In removing the postings from the public domain, though, it may also make it harder to bring the critical transparency to Google Maps that it obviously needs.
