I am an affiliate who has crystal casinos listed as EVIL. I warn players to stay away. The reason is simply because they steal winnings from players. An affiliate with an active membership cannot risk their reputation on this type of scamming casino operator.
The bottom line is that these casinos actively try to cheat and fool players. I cannot believe that they are still in business. No player wants to play at a casino where if they lose, they lose and if they win, they lose. It should be common sense.
