The blacklist was original developed to prevent bad actors from using bid bots.
And that is why the integrity of your blacklists remains largely questionable because you still have people who were erstwhile bid bot abusers on it even though the bots are now moribund, even though you were one of the largest beneficiaries of the bid bot era. There is a moral question mark in your actions.
You are like a weed dealer (bot owner) who now punishes everyone who took weed in excess (bot abuser) even though the weed dealer profited more from the sales of the weed (votes). There is a moral question mark in your blacklist as long as you have erstwhile bot abusers on your list. I trust this meets you well. Regards sir.
I mostly devote my time to finding abusers, not catering to them. I don't have the time or man power to listen to all the spammers saying they are going to stop or changed ways when 98% of them are lying.
There is a famous legal maxim credited to Benjamin Franklyn that says, it is better for 100 guilty persons to go unpunished than that one innocent person should suffer. You should care about the 2% me thinks.
