What will happen after giving the response on deleted person's discussions?

Today when I comment on the discussion related to alarm then I saw lots of other similar discussions. I click on one and see the person account is deleted but their discussion is there and I like discussion so decided to respond on it. What will happen no consider my comment or deleted my comment or not payment for my writing because that person's account is deleted or no effect of deletion of account. I want to share the discussion link but I think this will not valid.
