You will run out of the people doing it remotely well very quickly though.

The high quality modding of askhistory, anthropology and other science sub reddits are provided by actual domain experts working for free. You can find someone to replace them, but the quality will plummet and the users will leave.

You're assuming that the current mods are already doing it "remotely well." There are no shortage of cases where people have been banned from a subreddit for ridiculous reasons, myself included (e.g. talking about studies that support safe sleep practices for infants). When Ceddit still worked, it was eye-opening to see how much shadow-censorship was happening, and for the most petty reasons.

The subreddits you mentioned are good examples where domain knowledge is a very desirable trait in a mod. But by and large, it's not necessary for a mod to have deep domain knowledge in order to be able to enforce rules consistently. There's a reason why it's called being a "glorified internet janitor."

99% of the unpaid jannies job is sweeping up the spam and crap.

It’s the 1% remaining that gets people pissed, and you can NEVER please everyone.
