Player who started this topic is SCAMMER. He used special software for Felix Gamin slot "Dark Mystic" abuse.
You should prove it, OP is not even active since December in this forum and he did not share any other big win from the mentioned game (Dark Mystic). How can you accuse him as scammer who abuse the game with a software? You have no proof as well on your new created thread, no proof that the win by software was happened in your site.
As much as it is very unfortunate to hear your side, you are still bound to prove that OP did indeed used illegal methods and means while participating in your casino. Since you have alleged that OP is a scammer, you have the duty to prove such accusation. You can also create an accusation against OP if you have the substantial evidence and if you also want to tag him for future safety in the forum.
Building a reputation on your gambling website is the most essential thing that you must do. If players complain on any delays, problems, or anything, then it would be difficult for you to build your player base, thus suffering profits on your end.
