So any outside laws allow them to operate this way and not be touched by any foreign laws even U.S based ones because you are using their service which doesn't allow U.S customers access to using their site anyways and they know that is where most of the flackback from those players being their customers would come from being the largest amount of sues coming from in any country in the world.
Why else do you think most of these casinos run out of and license themselves there? To situate themselves on the shady line of the laws to protect themselves from just that reason. By being sued for laws they very well know they are breaking in any other part of the world.
Government payoffs to turn the other way when these casinos head quarter and operate out of their region of the world.
It is at a disadvantage to the players who actually believe in using these casinos who originate or even have anything to do with Costa rica.
Sad isn't it? But so very very true and they know very well this fact and just continue to know they are protected where they are.
