Comment:
True, but -- as far as I've seen reported, I am not a security expert --
all that means is that you have to work a little harder and make more
requests. Hence "slow down". XORing a one-time-pad onto the secret means
that the secret is never repeated between responses, rendering the attack
impossible.
