I won't post links but there is a post here, on steemit.com, that encourage people to upvote it for the chance of winning an "iPhone". Author says that it's "win-win" for both - him and those who upvote. But I strongly believe that this is will be "epic fail" for this young, but fast growing community.
Just imagine a day when you open steemit main page and you'll see nothing but posts like that. Is that what we want for steemit?
