Have you considered these:

1. Misuse of bots
2. Shit contents like whale wars, complaints, few pics, 2 liner posts, etc. nonsense on trending page.
3. Flagging for fun or to remove personal grudge.
4. Witness/Delegates who comment or posts once in a blue moon.
5. Wasting tremendous amount of money on meetups/fests, where nothing really good happens for the steemit community, but its getting worst day by day.
