On: Captchas To Keep Idiots Out Of Comment Threads

Not that that is a place where idiots are likely to venture, but I remember this "captcha" for the Arch Linux forums:

  What is the output of "date -u +%W$(uname)|sha256sum|sed 's/\W//g'"?

(https://bbs.archlinux.org/register.php)

That's a nice one. A bit like "how many were going to St. Ives" or "what color are the bus driver's eyes."

EDIT: whoops, I interpreted it as 's/\S//g', which I assumed would discard everything.
