Hi. I’m the author of the site (using a BugMeNot account).
The actual article on KittenAuth is here:
https://www.thepcspy.com/articles/security/the_cutest_humantest_kittenauth
I’m currently taking on-board all suggestions (of which there are a lot) for the second version that I’ll implement for myself.
After that I’ll be teaching myself enough PHP to work on creating several plugins for all the major blogging apps.
If you like it, spread it around the net. If you love it, come on in and click an advert. If you adore all the cute furry animals and you’ve got a spare $2 languishing in a paypal account, hit the donate button so I can feed my kitten =)
