Google does it. Wikipedia has local lawsuits. I'd argue that this is part of the (unfortunate) reality of running a global project and, as commented elsewhere, the only safe option to avoid lawsuits is to pick a set of laws (US here), have lawyers for the same and .. restrict _everyone_ not under these laws to access the resource. If you block Germany for different copyright laws, why not France? Poland? Canada? (My naive assumption is that these laws are not the same worldwide and differ in gazillion edgecases between countries, even if otherwise somewhat compatible. That assumption might be wrong of course. IANAL)
