So technically if something like that is part of the algorithm ...

            if (customer.RefusedToAdvertise) { foreach review in Reviews ( if(review.Score > 1) { reivew.visible = false; } ) }

Yelp can then say that "employees can do nothing, everything is done by the computer" and that would technically be true. And nothing can be done because they can not be forced to reveal the actual algorithm and any case will be thrown out of court?
