@darius Weird! I thought the usual CAPTCHA approach was to provide a random mix of known and unknown images, then use clever statistics and aggregation to get certainty about unknown labels. Sounds like this particular implementation is buggy.

@adrian yes, I was simplifying when I said "it doesn't matter what I select" -- I suspect I can select stuff that is wrong but also close enough within a threshold of expected-wrongness for it to pass. OTOH in the next captcha I told them that an airplane was a house and they were like "sure thing man"
