I see Google moving to use their 'news algorithm' to fight this kind of thing. When a news site gets linked to a great deal real fast then it shoots up in rankings, but once that super-high load disappears, suddenly as other news articles become more relevant, then Google basically blacklists that previous article despite that it has super-high backlinks.

Could Google just see a site get 1,000 +1's in a week and then never get another for 2 weeks and then blacklist it like the above news algorithm?
