How about no bots, and accounts with no investment/community interaction cannot flag or upvote with any SP. Their SP comes into play once they reach the MIR (Minimum Interaction Required).
MIR to start voting with your SP combats the growing armies of vote bots that cannot be eradicated due to their accounts not having any material to vote or flag.
Or the easiest option. Remove user BernieSanders from the platform permanently. Everyone else seems to be able to have a discussion without calling someone a "cuck." Not to mention he represents the community as a whole as he holds a witness position, and he does so in a fashion in which will deter any talents from joining such a volatile environment, especially when it requires a 13 week investment to get anything out of your efforts. Why buy SteemPower when you can just buy STEEM and not have to put up with this user.
I prefer MIR, which would force BS to find new loopholes, and would allow for users to organically grow, even if he doesn't think their content is up to his arbitrary standards.
