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'm pretty sure you could bring them up in the court itself, so there's no need to set up an online one though afaik it's limited to where the casino is located or the country it's registered at. That's why licensed casinos are preferred more since they ensure that the casino is actually registered somewhere and is legally doing business. Also OP I think you made a mistake, I think you meant censored? And the only reason really why it's left as such is because the user doesn't bring it up to court. He posts it instead in the sites forum and other sites that have gambling-related threads (like this one) and lets the people know, and it stops there. It isn't really censored per se, but it mostly has a limited impact.
