Ignore them, OP.

Most are moved by some misguided vendetta against mentors and regard them as slaves who should have no rights whatsoever. The toxic epithome of the "coddling bad gameplay" mentality - force mentors to carry the other players no matter what, even if it's glaringly obvious the duty won't be cleared until timing out.

P.S.: if people don't want to learn, trying the whole duty time won't change a thing.
