Your plan sounds complicated tbh. I think I'll have to read it again properly tomorrow in the day when I'm more awake.
I do think you make a good point about extractors and the spammer who doesn't power down. Hard to say who is better/worse/lesser of two evils.
For now, I'm interested in those super high KE (that person with >46 KE 😱) you're targeting and quite bemused by their reactions and justifications. Is there any kind of tool you're using to downvote those? Or can I just follow your auto(down)votes trail in some way?
