A photographer, not to be confused with a bumographer, who purchases a camera for the sole purpose of taking photos of women in sexually exploitive and provocative ways. They don't possess photography skills and akin to the "guy with a camera."
People with compulsive shopping disorder are often unaware --- or at least unwilling to admit --- that they even HAVE the problem, and therefore, autobuyography-writing is rare among these individuals; they are often obliged to have outside observers --- who DO perceive the financially-unwise patterns in the affected people' lives --- write the compositions for them.
