The worst abuse on steemit comes from spam accounts, account farming and unnecessary self votes of large whales actually. Far more coming from these places than bid bots.

I cannot agree more. Absolutely true. No form of abuse is bigger than spammy content getting rewarded and vote farming.

I meant that people are using bid bots to tear apart the essence of reputation algorithm. Having higher reputation certainly helps because it is a social signal. Any social signal helps users get attention (and votes). I would still voice my opinion for upholding the purpose of reputation system.

Regarding having a shared blacklist if you will, I think it is an absolute need at the moment. Any people who are handling abuse should collaborate. I know @therealwolf is using blacklist of @themarkymark for regulating SmartSteem. More collaboration is needed. Steem Cleaners' 5500 strong list is gold for fighting abuse.

I really appreciate your thorough response. I also appreciate your concern for the integrity of bid bots and reward system. I share the same concern but you well placed to make things happen. Best of luck!
