Also, when I see a newbie whose first post is on a reputed gambling site I become surprised and ask myself where you were before the scam.
I don't think average players do any kind of research about a casino before they choose the platform to gamble. I didn't get your point BTW, it would make more sense if you had said why they did not check if the casino is reputed or not. If it was 1xbit, I would blame OP because he chose a proven scam casino. But I won't blame OP because Rollbit is a reputed casino.
About this particular case, OP created this thread on 25th October and wrote another reply here. Since then, they did not come back to the forum and did not post anything. It was too early to create a scam accusation. It is normal for casinos to process withdrawals in several hours. I guess OP created the thread too early but later got paid. Otherwise, he would come back and write about his accusation.
I tend to believe that OP's situation resolve itself after certain passage of time, that's why they didn't bother to come here to explain, answer, and/or give several evidences to support their case. Afterall, the basic facts of this case is that OP is KYCed and they simply have a pending withdrawal.
With above reason, I think it's safe that I'll put "resolved" on this case when I update my list [I had an unexpected meeting last Sunday, so I can't update my list by that time].
