Things dont really work the way they should be due to many reasons.

• Selfish users who are busy upvoting their own comments, instead of checking other posts and rewarding them.
• Many unnecessary Bots are posting in the comment section hunting rewards.
• Phishing and it is really sad to see it happening, but it is the worst nightmare. Stealing accounts and transferring the money out of Steemit.
• Communities upvoting each other, and even their low quality content.
• Spammers upvoting their spam comments, but not upvoting your post.
• Whales fighting each other and not giving attention to whats happening.
  etc...

Many things need to be controlled and fixed to have The Successful Dream Platform that we all wish to see.
