People will never listen to you no matter whatsoever proofs you may give to them.
Most of them are either shills of competing sites or most probably some buthurt gambler who coulnt afford to loose what he actually gambled with and now is really pissed with loosing all that money.
to be fair I can't blame him cause when I was first introduced to a dice site I thought the same thing every time I had a long losing streak
at the end people learn the lesson the hard way and then they realize that it's not the site's fault
some gambling affiliates on youtube for example mislead the newbies with false informations , check out this guy who keeps telling his followers that his methods work on the casinos that he promotes
