See point 14, where they clearly said they reserve the right to ask for valid identification of a user under the KYC procedure for some cases. For asking KYC you can not say they are scams. Maybe they have found something suspicious.
They stated it that KYC is required for withdraw. Check it again.
But if the user is suspicious, they can ask for KYC again. I have seen many sites that like doing that, asking for KYC again or asking for another documents to make sure that the user is not trying to manipulate with fake identity.
I asked them on email if they have found any suspicious activity from me other than winning approx 100 euro. I asked if my IP or device was used on other accounts. They just do not want to pay, is that simple
then if that is the case since you are already convinced (according on how you are answering here) then just accept that fact and move on, and if you wanted the forum to tag them or do something for them to comply or pay you back then sorry to say but the forum cannot force the site to perform such that , and besides you did not even bring any proofs here about your convo or something to support your claim.
and besides don't be fooled of those banned because most of the casino trying to lure their crypto players on that promises but if you through their ToS then you will find that in any way they can ask KYC if they think you are suspicious or something relevant to that and this is what happened now.
