Google temporarily disables Map Maker due to pranks. You know who you are, Mr. I-put-Edward-Snowden-in-the-White-House.
"As some of you know already, we have been experiencing escalated attacks to spam Google Maps over the past few months. The most recent incident was particularly troubling and unfortunate - a strong user in our community chose to go and create a large scale prank on the Map. As a consequence, we suspended auto-approval and user moderation across the globe, till we figured out ways to add more intelligent mechanisms to prevent such incidents."
