They are spamming JacksClub.io chat with links to JackBet.io and user registered nickname Admin.
Not site to trust.
Does the one spamming really the admin of Jackbet.io? Too many frauds that are popping up on telegram and it's easy to manipulate it with a fake account. If so that's the real admin as well for the Jackbet.io then that's not nice imo to spam another chat room just to promote the the game.
