If people buy reviews to paint a picture of a good standing business, what would stop the competition from buying people to tarnish a competitors reputation to have an advantage in the business?
I feel there was some paid agenda against sportsbet.io some months ago but because the accusations never had any facts and substance to them up, they never lived up for too long. Hence, it might be easy to tarnish a casino's reputation but it cannot be upheld for long unless there is some truth behind it.
