I've seen Google slap a site for something similar. An attorney added 20 new pages to his site, all having to do with divorce. Links were added to the main navigation of the page. Anchor text was like "Miami Divorce Lawyer for Artists", "Miami Divorce Lawyer for Actors" etc. After the site got crawled their rankings dropped. Pulled the links (kept the content) and rankings were restored in a week.
I would call each one what it is.
