Something I learned very quickly the first time I started a business doing online sales to a global market is that while it might be very un-PC to talk about entire nations or cultures with stereotypes, there certainly are patterns in how people from different countries behave, and there certainly are some places where it may be economically justified to decline all sales because the risk of fraud or other abuse is so high. The UK has never been a particular problem for us in that respect. Maybe that's because it's our home country and we are somehow more appealing in how we present ourselves. Maybe it's the market we're in. Maybe our pricing model makes it less worthwhile to try to rip us off if you have a typical UK income. Unfortunately there isn't any truly reliable way to determine why people from some places are so much higher risk than others. But the numbers don't lie. FWIW, I think the Germans are probably the best customers we've had. IME, they're invariably courteous and very rarely cause trouble. And even on the rare occasion when a German breaks our rules (probably unintentionally due to a language barrier or the like) the response to a polite message informing them of such and asking them to stop is usually a polite apology and immediately correcting whatever inappropriate behaviour was happening. So there are definitely cultural outliers in positive directions as well as negative ones.
