I have played massivecraft for about 1 and a half years, and I recently decided I wanted to donate and become a premium. I saw that donations are ONLY accepted through PayPal, which I am currently banned from.
So, I suggest that Massivecraft give the option to pay some other way, like Google Wallet for example, or anything else that isn't Paypal.
So, I was buying a new laptop on eBay for about $720, and about a week after paying with PayPal, I get an email saying that PayPal suspects me of fraud and have kept my money while they "investigate". Weeks of angry phone calls later, they promise to send my money back within 30 days. After waiting, I finally get it back and now I can't use the same credit card on PayPal anymore, I guess it's my punishment for daring to ask them to give me back my $720 that they took for absolutely no reason.
