That seems to be happen if he found a new dice site to troll up so maybe helping him to find out new or even old which he didn't discovered yet is not a good idea since he will just spam his craziness once he lose his money there. Maybe this is part of revenge when he lose his money so maybe its good to let him seek what he want since helping him is like tolerating his deeds here so better ignore this kind of person and newbie gamblers should always find the feedback of OP as invalid since his reputation says that he doesn't have any credibility here.
I have the same feeling also. That's why he doesn't want the old sites anymore because his scheme was already busted. And he will try new dice sites for the hope that they will fall on his fraudulent trap. If he is sincere in trying new dice sites. He can easily check each casino on this gambling board. There's no need to ask as he can easily do this job, read the thread and try. By the way, this should be in the gambling discussion board not on this board.
