There could be three explanations for fake FB likes:
1. As mentioned in the story, click farms trying to cover their tracks by clicking FB ads.
2. Competitors creating fake profiles and fake likes. It seems like a cheap way to drain out the advertisers budget.
3. FB itself creating the fake accounts / likes. I know it is implausible, but there is a profit motive, so I guess the possibility should be considered.
