I think getting a few 4 star reviews might actually be good. I know Etsy doesn't have review fraud like Amazon, but when a shop has only 5-star reviews it seems too perfect to be true. When I see they have some 4-star reviews it makes them seem more legitimate because they aren't buying reviews. Now a 3-star is when I message them. And many times they accidentally did it and meant to put 5-star.
