Hi all, (apologies if this is not the correct place to post this -- i didn't see anywhere more appropriate) I recently tried to sign up to the Arch wiki, but I was met by the following CAPTCHA. What is the output of: pacman -V|base32|head -1 and I had some issues with this that I'd like to share, while I get the reasons this captcha system was put in place (to prevent spam & to ensure the user is currently using an Arch system), however I don't believe the current captcha is a good solution. First of all, my problem is with the requirement to verify the user is currently using Arch, as the Arch Wiki is a very popular resource in the greater Linux community as a lot of resources apply to software that is commonly seen on other distributions, for example, I wanted to make a change (which I encountered configuring an Arch system) that was useful to everyone who used systemd, anyone, be it an Ubuntu, Debian, Fedora, etc user may have found on the Arch wiki. While I think (I'm not sure, anyone is welcome to prove me wrong), the little number of users trying to post good faith, however, off topic, non-Arch related content, should be stopped by having their changes undone, and people who are Arch Linux users may still fail the challenge (i.e. using a non-arch system at the time, using an Arch system with an different version of Pacman.) However, my second larger problem is that it doesn't seem that it'd be a very good spam prevention mechanism. The CAPTCHA seems to be the same for all users, and changes very infrequently. (pacman version 6.0.1 (according to https://archlinux.org/pacman/#_releases, released in September 2021) and 6.0.2 (according to https://archlinux.org/packages/core/x86_64/pacman/, released in November 2022) were released over a year apart, so any spammer could define the captcha challenge for the Arch Wiki and post spam for many months. Determined spammers could even write a system to run the command inside a Arch Linux container and cache it until the challenge does not work. Ideally, CAPTCHA systems should be - hard for computers - easy for humans - accessible - unique for every request. The current CAPTCHA system fails every one of those requirements, I'd suggest either using a more common captcha type (such as Google reCAPTCHA, hCaptcha or a generic maths challenge), switching to more human friendly, easily Googleable, but still domain specific questions (i.e. "in which year was the Arch Linux project founded"), less ideal, but you could use commands that always produce the same output (i.e. "uname | base64" should always produce "TGludXgK" on Linux) Thank you.
