It seems a lot of problem now that's coming to Duckdice, when you checked their ANN thread you can see a user name nomercy complaining about the Duckdice's ToS about rakeback/cashback? I'm not sure about the details but I think they should resolve it and also in regards with the OP of this thread I don't think your claim is valid not unless you give a proof of your clams such as shady behavior and the fake license they have.
i have posted about theire fake gambling licnes.thats a solid a proof.Read the post you maybe find it
Upon reading the response of the majority here, it seems like you are going to be needing some more evidence than this one, real hard ones, if you want to push through this accusation and fight to prove their deeds that you have claimed.
