Apparently many new reviewers approve crap that:
- is just crap 💩 (or spam)
- add typos, chatspeak and other noise. plz help me kind sirs!
Giving them some audits to begin with would probably help educating them. I'm not talking solely about the Markov-chain spam/vandalism although one of those audits should be like that. There should some perfectly fine edits, some that add backticks and similar crap and some that "correct" a link while changing it into an obvious spam link.
I'm not sure what the action for failed audits at this point should be. Possibly displaying detailed information about why that specific edit was invalid/valid, banning for a short (1 hour maybe) time and then showing another set of review audits. Only after passing the full set of "new reviewer" audits the user would get to review actual edits.
