You are running Mailman 3, which has several malicious user mitigation strategies available to it.
Even using a CAPTCHA on subscription removes most of the scum.
I've not used MM3 - still on MM2 - so I can't help directly, but the <mailman-users@mailman3.org mailto:mailman-users@mailman3.org> mailing list is where I would start.

This wont overcome the problem of those actual vermin who subscribe with sole intentions of spamming or abusing the list, Pablo's idea of new user moderation is the closest workable solution.
It does, at least by reducing the amount of stuff generated by script kiddies and 'bots.
I neither have played with MM3 or this hyperkitty thing, but seems it has flaws that are not helping.
Hyperkitty is just a mechanism. Ask the people who know how MM3 works for advice about the problem.
It's not like the problem is new, but even requiring acknowledgement of subscription reduces it a lot, and adding in a CAPTCHA even more.
