As you all know our current CAPTCHA (ReCaptcha v2) is simply not doing it, and MW.org itself says "ReCaptcha has been cracked by most spambots targeting wikis, mainly due to its accessible captcha alternative."
This is why we must upgrade to ReCaptcha v3. Unfortunately, the process doesn't seem to be getting anywhere upstream so I feel like we only have two options: either 1) we fork all of ConfirmEdit and do it ourselves or 2) we integrate ReCaptcha v3 into MirahezeMagic. It is useful to note that there is already an open PR upstream that would facilitate the work for us - https://gerrit.wikimedia.org/r/c/mediawiki/extensions/ConfirmEdit/+/539679
I've set this to normal priority as we get regular complaints about spambots and we really need to do something about it. Until now I've waited a bit to see if something would move upstream but it doesn't seem to be happening at all.
