Do you mean that you'll intentionally not build on blocks from Kano.is? I think you need to clarify what you mean by blacklist.
We will not build on his blocks until our local bitcoind got received and verified them in full. This guy leaked our IP addresses to the public, I pm him kindly and begged him to remove them but he refused. If we ever got DDoSed due to his post, we have no choices but point our domains to his pool.
