this is the second plug i've seen today for mCaptcha. and i can see the utility, i've actually got a spot where it would be perfect and plan to implement it. but it's absolutely not a captcha: it is not a test to tell humans and computers apart. it's a test that can only be completed by a computer. its only utility is to be expensive. it's not a test to determine if there's a human behind the computer, it's only a test to determine if the computer has more resources than it currently needs, and can tolerate wasting some of them for a while.
