Would like to add that; since I had several customers, whose paypals were banned. The worst thing about this "ban" it is like paypal itself doesn't even know the actual reason of why they do that. What I mean is that even @Berserkdhimself said that their answer was " due to policy violation" , paypal simply doesn't say THE EXACT REASON of what occured this "ban". Which makes me think that actually something else is happening here...
Might sound retarded.. but maybe ncsoft is pushing them to ban these paypals with some copyright-stupid laws about their files,like they do with twitch and paypal kinda agrees to that. Because they will have to deal with less "refund reports" ( because as we know , many donators are refunding their money back).
Or I am just fully wrong about the whole concept
