years ago in the poker business this happened quite often.
smaller players (in the poker vertical) tried to kick out bigger players this way. we saw it, we were worried, then google took care of the "poker" vertical overall (the big "poker" shake up of 2009).
i would personally just report it to google. if i would not get a response via the "reconsideration request" i would fly to one of the SEO conferences and talk with one of the google spam guys there. would be a much better option than sending idiotic threatening letters to random websites.
