I've seen this too - a fake business (one selling bait-and-switch low quality services through online storefronts) had many 5 star reviews, and if you clicked into their profiles you'd see a smattering of 5 stars reviews all across the country, sometimes in different countries. Some of them also gave a few 1 star reviews to a few places, probably the flip side of the same review selling business.
