Just what the world needs... another way for Google to correlate everything you do online with your personal ID so they can show you more ads.

I was thinking just one more way to make having a small business profile online will become untenable, if simply anyone can comment on search results.

With local reviews it is expected at least that you are a customer or have a direct relationship with the business and in most jurisdictions there could be legal recourse for posting fake reviews.

This sounds like a free for all.
