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.
The problem is something that has been around for years, and your intention to create the court seems important, but it's something that wouldn't work.
The best tool we have is the forum itself, where users bring the problem and present their evidence, in the same way, sites have the same right and the community is the one who decides who is right or not.
Anyone trying to steal will be penalized... in case a notable user will get a "flag", in case of a site it will be spotted forever in the biggest crypto forum (a very bad advertisement against it).
What would a court be more efficient at than that?
