They have spammed up the reviews with a bunch of 5 star reviews from various JWs from all around.
I did the same thing. Also noted that all the reviews, even for halls that have been closed and sold several years ago are made by the exact same four or five people. The same over-the-top gushing 5 star reviews of the congregations, most of them in only the last eleven or twelve months. And having visited all of them over the past decades when I was not FedUp I can safely say the reviews are lies!
