There have been so many accusations and counter-accusations on the subject matter of fraud so many players have come out with evidence of scams against some sites while the operator of those sites come up with counter-accusations that players violated their T&C.
I think it will be proper if an online accredited court is set up to judge such cases, rather than leaving them uncensored.
I believe you are in the right community when it comes to concerns about fraud gambling websites.
You wouldn't want to pay thousand of dollars to pay for an online court to investigate your case and that could potentially become one-sided.
This forum has been very effective for resolving cases of scams or fraud. If the gambling website has a bad reputation in this community, most probably it won't come out as most recommended gambling site for everyone.
In most of the cases it is the user that raises the accusation against the gambling site and most of the times it is the user who is at fault.
I have seen cases where the gambling site was proven guilty but it just gets added to the scam list of sites.
While it does help in preventing more users getting scammed but that particular user doesn't recover from his losses.
I haven't seen any user getting their funds back in such cases where the forum has concluded scam accusation cases.
I just wish most times that a closer look at some accusations made by the complaints be looked into closely before tagging a site a scam gambling sites because as @pawanjain stated gamblers sometimes are at fault and want to pour out their frustration on the gambling site. But the fear now is most of this sites operate without license and gamblers find their side of the story unrealistic
