My personal view has always been not to respond, in part because it comes across as controlling.
All your responses were fine, fritmdly and complimentary and grateful, but when I read them I thought a. The response is not relevant or needed for the general public, it’s more a private response if anything so it comes across as faux, a bit helicopter monitoring of reviews or too personal plus
b. I found it distracting. I was more focused on your response (that added nothing to the great reviews) and as such it diverted my attention from the content of the great reviews (that you would want me to focus on).
My 2 cents
