That's precisely correct. Forcing Facebook to accept pseudonymous users represents a fundamental change in the nature of the service. Facebook can and should suspend service in Germany. It's unfair to users from other countries to have a bunch of anonymous idiots spouting off.
That's funny because half of my German FB friends (mostly female though) are using a pseudonym. A popular convention is to leave off half the letters of the first and last name each. So Hans Meier would be "Ha Me". These guys are writing the least inane postings in my news feed.
