Mike Blumenthal covers Google Maps news like I cover search news, he doesn't miss anything when it comes to Google Maps. He has been on top of the Google Maps closure bug that was published in the NY Times and responded to by Google.
The lastest on the topic is Google has a fix. Google told Mike:
As promised, we've recently made a change to our process of displaying when a business has been reported to be closed on its place page. More specifically, we have removed the interim notification about a report having been made so that a listing will only be updated after it has been reviewed by Google and we believe the change to be accurate.
The good news is that Google will only report out a business as being closed after it has been reviewed by Google. There will no longer be the interim message of "Reported to Be Closed".
Anyway for more history on this topic, see Mike's blog.
