I have the same experience. Pages with poor content get high CTR and V. High CPM . Main website draws visitors through Search engines. Still my site is not very highly ranked so I have to use adwords. My poor content pages pay for my advertising cost in promoting my main website. Maybe not very ethical but seems to work.
This is the primary reason why MFA 's exist. The good part is that they will rarely get 'free traffic'.
