Thank you Guust
If we take an example, you have a business and 5 review from other people are with 5 stars, so after i came and i write 15 reviews with 1 star, you business end with 1 or 2 star after that.
a solution can be added next to the stars an option check / uncheck the opportunity to rate the stars ??? what do you think ? or better 1 review time.
