each Goodreads user has a setting on the account page to enable/disable the readability of the submitted reviews ( "allow partners of Goodreads to display my reviews" ).
The api_blocked_count tells you how many of the queried reviews were actually filtered out from the XML output. ( You are using per_page 30 but you are getting <30 reviews as some of them belong to users which flagged that privacy settings).
