The wiki just asked me for the output of running "pacman -V|base32|head -1" as a captcha.

To put it mildly, this is a *really* stupid idea, for a number of reasons:

- This doesn't work if you are using the testing repo (which currently contains a newer version of pacman than the core repo).
- This doesn't work if you are on a system that hasn't yet been updated to the latest pacman version.
- This doesn't work for users who are not currently sitting in front of a machine running Archlinux.
- Asking users to paste random commands into their shell seems just like a really bad idea in and for itself. The Archlinux wiki is supposed to be about Archlinux, not about questionable social engineering techniques.
- This doesn't really work as a captcha since it can be easily circumvented.

Also, if been asked the same captcha multiple times. If there is only a single captcha, just spare users the nuisance or at least use a cookie so users don't have to solve the same captcha over and over again.
