You are doing it the wrong way and also mind-reading the rules of the forum, because I can see that you are making a duplicate thread because of you already have one in the gambling discussion board why create another one here again?
This act will lead you to an account ban, and you may not be able to create the right accusation against the casino in the future, this a forum with rules and regulations so make sure you follow the rules to avoid penalty and you are already committing an offence already.
Op if what Wiwo is saying I'd right you have to delete or lock one of the threads so can create accusation thread against the casino in the Scam Accusation Board. Op Wiwo had just told you the truth about the whole Stuff. I call this as thread farming, that is you are creating one thread in two different boards which is against the rules of the forum. If you ban the yours is gone because if you create another account for the same purpose it will be it will be a tag of ban evasion against you. So to save your life, prevention is better than cure. Lock one the thread now.
