All the real-time location based stuff is after my time, but it definitely looks like an attempt to generate more known-good reviews. Possibly for better training data for modeling. I'm not sure that the historical location data is as useful as you might think - there's often a large temporal gap between the experience and the review writing. Google does have a big advantage in verifying good accounts through other activity, but that advantage shrinks dramatically for new accounts. There's still some things you can do, but at the end of the day you're only willing to assign so much risk to a brand new account based on metadata.
