rob, Reb Moshe is very clear in his psak that WE CAN dispute the sincerity of someone who went trough the mechanical motions of conversion. Again, directly from Reb Moshe’s psak:
It is clear and obvious that he is not a convert at all even after the fact…
He said in such a case that the person was not a ger in any sense whether for leniencies or strictness…
It is simply obvious that such a person is not considered a convert.
