What is a "real philosophical system", and what distinguishes it from an unreal or fake philosophical system?

In particular, if a person who is not a professional philosopher has a set of beliefs about what is knowable or what is moral or what the nature of consciousness is, and if that set of beliefs is unusual, is their set of beliefs a "real philosophical system"? Conversely, if that person is a professional, full-time, employed philosopher and their set of beliefs is very popular and influential, is that set a "real philosophical system"?
