Catcha is a far better (and more fun) solution. It’s based on the theory that only humans will recognise a cat in a series of photos. Displaying three images from Instagram, one of which features a cat, you just select the photo with the feline in it – and voila – you’ve proved you’re human.

genius.
I’m wondering if it would be possible to teach an algorithm how to spot cats. Maybe using some sort of eigenface for cats. An eigenpuss.
It’s been a long & busy day, go away.
Teaching an algorithm to recognize cats might render it useless for spamming, actually, as it would just spend all it’s time dicking around the internet looking for cat pictures because 01001111 01001101 01000111 00100000 01000011 01000001 01010100 01010011 !
Can’t stop laughing.
