What stops me now to make a new account. Rent some steem power and kill all the accounts that downvoted me? What stops me to make spam on other accounts and recover my losses? Do you think the big guys that have tons of sp will upvote those who will have 0 reputation? Everyone is for themselves here and no one cares. There are people who seek help, who try to raise funds for their surgeries but all you do is to upvote big whales and make them even richer.
