My advice is, provide strong evidence and what the cause of shady behavior that OP meant. It is nothing or does not make any sense if you don't have evidence even we know that this gambling casino doing shady behavior a long time ago and how did you get involved in that casino if you know they have shady behavior from the start.
Even if the OP provides us with solid evidence, what difference it will make to the duckdice. Their rating on the trust pilot is 2.3 which is very poor. In such cases, i would rather ask the OP why would he is so willing to play on the casino which does not have a good rating. Why not play at trusted casinos ? There is no shortage of good casinos.
Their ANN Thread even a "Self Moderated" in which sign that they are hiding something and don't wanna let cases to be filed in their front .
