Conspiracy theorists do not work that way. They convince themselves of the validity of their belief and, regardless of all other evidence do not recant. In fact if overwhelmed by opposing evidence they usually turn to the logic of, “Hmm, this person seems intent on changing my mind. Who are they working for?”
In other words the more someone tries to convince a conspiracy theorist that they are wrong the more they are certain they are right. This is why some people still believe the earth is flat.
