It is so easy to fool others with such campaigns. I make two alts. On the first, I claim that I would pay 0.1BTC to a lucky follower when I reach 5k followers. When I reach the mark, I show a fake transaction tipping my alt and finally, I lose nothing but gain an account with 5k followers. I sell that account for 0.25BTC. People need to think before blindly giving valid information or here, blindly following others in a campaign.
