capable of processing an entire chain.

I'm not sure why you would want to process the entire chain rather than monitoring it in real time for posts that meet a certain criteria and then punting them to a checker. Maybe that's what you meant. The bulk of hive traffic is not blog posts. Why would I want to feed splinterlands battles into a plagiarism API for example? There should be an arbiter for that built into the system. If Cheetah for example were processing token sales on hive engine and the rental market on splinterlands, and checked them for plagiarism, I would argue it's poorly designed.

It's a shit job, everyone is disenchanted with it, everyone thinks not enough is done, its thankless.

You'll get no argument from me here, which is why as much as possible should be done by a 'trainable' algorithm.

We go through this every six months or so on average and then no one cares anymore and getting feedback on anything is like pulling teeth.

For me it's more of a question of 'out of sight out of mind.' If it's not happening on chain, it didn't happen. That is a problem, because it should be on chain. Ideally if someone breaks a rule, I should see their dossier posted in a reply. You plagiarized, here's a link to what you plagiarized, and here are all of your past transgressions. If I see someone I recognize was downvoted, I shouldn't have to run it down on Discord. From what I remember a large percentage of your time on discord is spent defending your actions because their impetus was not evident on chain.
