i think the post earnings should be fixed in steem...
For example:

• double the votes on accounts that earned less then 1000 dollar in he last year
• double the votes on accounts that earned less then 1000 dollar in he last month
• double the votes on accounts that earned less then 100 dollar in he last year
• double the votes on accounts that earned less then 100 dollar in he last month
• double the votes on accounts that earned less then 10 dollar in he last year
• double the votes on accounts that earned less then 10 dollar in he last month

Of course only for verified accounts...
