So far, 1Win casino is amongst the best, transparent, and reliable casinos in the world, and I have not seen many complaints about their services anywhere because they serve their customers diligently, and for their account to have been banned, then there is something he must have done wrong because 1Win carefully take thier time to look into matters before they take actions and they act in accordance with their Terms of Service so before they take action, they must have taken a critical look into such matter and made a resolve. So if anyonegets banned, then they must have violated a particular rule of the platform.
All complaints are being addressed; they just need to accept the decision if they did indeed violate the casino's terms. I'm sure 1win is open to arbitration and can defend its rulings.
I'd like to believe that their announcement thread here helped boost 1Win's popularity. They have a venue where gamblers can address their issues and post their contests and promotions, of course, with the support of the 1Win community here.
I hope it will stay this way, with fewer or no complaints and continuous promotions.
