What is the difference between verified and unverified moderator?
Will the payment of my services in the marketplace depend on it?
The difference between 'Verified' and 'Unverified' moderators is that Verified moderators have a real world identity associated with their Marketplace userID and therefore if they decided to abuse their powers as a moderator (such as by colluding with a vendor) then the wronged party would be able to being legal proceedings against the moderator as they would know their identity. An Unverified moderator on the other hand would be anonymous.
Then why even create unverified moderators if it is needed only for fraud?
I think all moderators should not be checked.
Unverified moderators can have good reviews and low pay for their services. In such cases, many users of the marketplace will choose this moderator.
