The main thing you can do is to not use PayPal. Unfortunately there's not really a good international online payment system. Netherland has the excellent iDeal system, and I wish the rest of the world would start using that or something indistinguishable from it. PayPal and credit cards are just too unreliable.
From a business perspective, maybe. But from a consumers perspective? Every time I have the option iDeal vs. PayPal I go PayPal, much easier and faster (just password and go!) -- and better uptime to boot.
