Google maps: how would you rate that place you visited last week?
User gives 5-star rating, clicks submit button.
Google (in an e-mail a few hours later): Your rating isn’t posted: "Unknown place" - What happened
The place you posted about was removed from Google services like Maps and Search.

Okay Google, if you want me to contribute to your free community service, what about making it more consistent and understandable for regular users?
