The problem is this was already tried before and it didn't work, the reward curve was tried before and it didn't work, flagging or downvoting has been a permanent part of Steemit and it hasn't worked. So now you make a hard fork with three different actions that are guaranteed not to work, and you have to think who this helps and as always it only helps those who have a big stake, the little guys will all come out losing and will do the logical thing, leave.
