Comments on: usability: Verification of Challenge Question and Challenge Answer http://www.spugbrap.com/blog/2008/06/usability-verification-of-challenge-question-and-challenge-answer/ This is a repository for my favorite scripts, regexes, commandlines, utilities, code snippets, tips, and other geeky things that might be useful to someone googling for an obscure solution some day. It's also a place to share my thoughts about companies I've dealt with, my favorite lifehacks, observations of interesting human behavior, clever and/or evil marketing schemes I've run across, and anything else I feel compelled to write about.

How does that work? Oh, I see how it works in the FAQ: "What's the point of displaying a pet that's up for adoption 3,000 miles away? Asirra is currently in beta-testing. The production version will do geolocation based on client IP address, showing users pets that are nearby. (If more than a few challenges are failed per day by the same IP address, we will fall back to using the entire image database, as a security precaution.)

It's neat-- they use pictures from PetFinder, so at the same time they are blocking spam they are also advertising animals that need a home. http://research.microsoft.com/asirra/ Have you ever the dog/cat verification that is used to determine if you are human?

The secret question is important for my pay pal account since they have such crazy rules for passwords that I can never remember mine. So I can see how hiding this data is important. : ) My favorite is the word verifications to foil bots that I can’t read.
