it seems coinzino.io is not clear in this case if they say the player is in violation please give specific evidence not to take the player money unreasonably and i think the player should be refunded
It's common practice for casinos to deal with the issue of freezing players' funds, I don't think they should be secretive into detailing when it's a common weakness in all casinos like IP usage.
By the way, this is
the representative coinzino thread in this forum. I don't know if they will be back or not anytime soon, at least the OP asked support or just directed them to this thread via PM.
