You are fighting the good fight but with little numbers it's a losing battle. Also, this is a delicate situation. On the one hand what you are doing for the community is honorable. The fact that other bot owners are also in agreement is good to see. However isn't this what the platform seeks? For new money to keep coming in thus sustain the steem price?
I only see headaches for you, the community and the user experience in general if all new whales that utilize the system are the subject of community backlash because they have the ability to dip in deeper. It's almost like the saying "my ball and you can't play with it".
Sure Trevon is a piece of shit. Only because we all know his actions outside of here though. In regards to steemit and it's exposure. I would be more inclined to make him work a little for acceptance. Put him on probation with the requirement that he be actively recruiting members in order to win back respect here.
After all, that is what he did best. Get people to trust his word and follow the link.
