I don't want some customers to leave reviews. What can I do?

There are a few reasons why you don't want some customers to leave a review.
One reason might be the ordering of trail orders. It's understandable the fact that you don't want to waste review request on yourself. Other reason could be the selling on Amazon, even though you can always disable the domain on the blacklist. The truth is that we highly recommend to activate it: customers can end up knowing your store and turn into your own customers.
