Didn't Google do this same sort of "recycling built trust in channel" when they bought Frommer's, gutted it, sold it back to the original owner, BUT kept the social media accounts Frommer's built up (with the old followers) and rebranded those followers into a new Google-owned Zagat Twitter account?

How is that behavior any less "bait-n-switch" (or influenced by money) than buying a site or renting some links?
