Mentor Requirements

[Seraphor]

That would be entirely the point I believe.

Anyone who didn't agree to hold themselves to a higher standard would not be a mentor.

No. You'd just get more self-righteous narcissists who think even more highly of themselves for wearing a Mentor crown.
You can not break the rules, and superficially appear to be helping, while still being a total asshat.

People who genuinely want to help other people will not want to run the risk of being targeted for higher levels of judgement via some Mentor policing system, or leave themselves open for harassment and abuse by people who know they can just 'report' you for a nebulous claim like 'not being helpful' and get your Mentor status removed.
