10. Encouraging everyone to click on a particular link for an advertiser to win something defeats some of the purposes of those ads. It tells the advertiser nothing about their methods and whether their ads work or not. This creates false traffic data which is used by our advertisers when they decide to renew or not. I was uncomfortable with the first one, but to use this method again to drive up traffic just seems wrong to me.
I would not want this method to be used during my own advertising campaigns here on BYC.
