How to address wrong view Did the Buddha give any teachings on how to deal with individuals spreading wrong view?

If someone is expounding their beliefs in a public forum under the guise of the Buddha's teaching, given the possibility that these views may misinform and lead others astray, does one have any responsibility to try to rectify this, and if so, what would be the proper way of addressing such an issue?
Of course others have responsibility to rectify the wrong views. There were several individuals spreading wrongly grasped views on Dhamma even during Buddha's time like Arittha, Sati and Sunakkhattha. Buddha's and other monks' reactions on such situations are detailed in Alagaddupama sutta and Mahatanhasankhaya Sutta. 

Buddha explains the plight of such people, as if grasping a snake from it's coils in the water snake simile in Alagaddupama sutta. 


  there is the case where some worthless men study the Dhamma... Having studied the Dhamma, they don't ascertain the meaning of those Dhammas with their discernment. Not having ascertained the meaning of those Dhammas with their discernment, they don't come to an agreement through pondering. They study the Dhamma both for attacking others and for defending themselves in debate. They don't reach the goal for which [people] study the Dhamma. Their wrong grasp of those Dhammas will lead to their long-term harm &amp; suffering. Why is that? Because of the wrong-graspedness of the Dhammas.

But for people studying the Dhamma for its real purpose, that is the cessation of suffering, Buddha's advice is to question him or an experienced monk when there's doubt. 


  "Therefore, monks, when you understand the meaning of any statement of mine, that is how you should remember it. But when you don't understand the meaning of any statement of mine, then right there you should cross-question me or the experienced monks.
