It would probably be more useful to run an arch container in something like distrobox. “Pacman -V” outputs some version information, which changes quite often on a rolling release distro. If you run your own arch box, you wil always be able to get the newest captcha code.
How is it a captcha if it’s machine-solvable?
It works because it is different from other captchas that all have ways to workaround already automated. Having a niche problem for a niche community works surprisingly well for weeding out the widely cast bots that are designed to solve the common captchas. Though it wont do much for a dedicated attack - I don't think they have had much of a problem with these and the mods can always change tactic when it no longer becomes effective.
Machines are better at solving captchas than humans. No, really.
You can install docker. Then...
$ docker run --rm archlinux pacman -V|base32|head -1

just paste it in terminal, it will give some random characters. Paste it in the captcha. This is honesty the best captcha I've seen. lol
OP states that he's running Fedora, which doesn't have pacman.
oh... sorry then
