This isn't really too surprising; this is the kind of problem you have when you try to automatically enforce real name policies. When you try to create a system which separates real names from made up ones, it's a lot harder when real names can have common English words which aren't ordinarily found in names.
Google+ had similar problems, if I remember right, and they ultimately solved the problem by getting rid of the real name policy entirely.
