  I'd be surprised if that's not true of the overwhelming number of people who post reviews on Google. I've posted several reviews in my home town, Google knows it's my home town from their maps data, that's a strong trust signal that Google could find a way to use to provide improved reviews. Google can probably tell if reviewers logged on to the restaurants wi-fi, that's a strong trust signal too -- Google could expose a trust status and still hide that they're essentially tracking our every move.

    Exactly. I could see it as "Verified visitor" for the various things that could indicate a real visit. Or some businesses use Stripe for payments, and they send me emails. Again, google sniffs all emails. This could be used to corroborate usage. Again, they could be faked, with things like GPS spoofing, and using Wigle to determine local wifi there to fake that. But again, each step there significantly raises the bar of fraudulent activity.
