Why don't you fight these big accounts? Because they are all using bidbot. For example you can fight with @berniesanders . Because i have seen using bidbot before. Why are you trying to exclude minnow accounts from this network?

Steem Blockchain is trying to grow. But you want to exclude minnow steemians. As I said, you really want to fight this issue. So start with these big accounts and let's see your true intentions.
