‘If anyone were to speak ill of me, my teaching and my disciples, do not be upset or perturbed, for this kind of reaction will only cause you harm. On the other hand, if anyone were to speak well of me, my teaching and my disciples, do not be overjoyed, thrilled or elated, for this kind of reaction will only be an obstacle in forming a correct judgement. If you are elated, you cannot judge whether the qualities praised are real and actually found in us.’ - The Buddha, Brahmajala Sutta.
It is blowing out of proportion already. This would be the right way to respond.
