Checking the fairness doesn't require that much work since most of the sites have a step by step on how to verify your bets.
Although relatively easy to do, I believe there are many gamblers who ignore it and they only trust sites based on the reputation they already have. Maybe I would have done the same if I played on a trusted site where they had evidence of game fairness which we can find on the site.
Fairness of the site towards users who gamble should always be considered important by all gamblers. This will remove any doubts about the site regarding its reputation.
Basing off with their reputation would be the main indication for some where they dont really matter nor care at all about it as long they do presume out or stick into those reputable ones.
It had been proven out by many or by the community when a certain platform had already some considerable amount of players.They wont really be reaching that
rank or reputation if they werent fair in the first place.
Fairness is the most important factor nor thing that we do mind off when we do gamble thats why people do make out some verifying and testing.
