Exactly how are they at fault for responding to the issue in the only way the site design can allow? Do you also blame Twitter for only banning people after they've posted something deemed to be breaking the rules? or that it takes 5 minutes to make a new account?

Unless you aren't attempting to imply anything about them being at fault. Although, as long as they are making that good faith effort to take down CP, they can't be taken down by the US govt at least.
