We had the same thing in contact-nl (a closed mailing list too) a few years back. The only solution turned out to be a nasty one: adding ^.* to the blacklist.

I've added another line to ban_list with ^sqoonart.* apparently the regexes in mailman ain't multiline?

In any case I doubt our list is the only one being affected so maybe we can block those addressed for all the lists?

Since a couple of hours I am receiving continuous subscription requests from addresses such as sqoon+random_characters@domain and sqoonart+random_characters@domain

I have added to the ban list the following regex to stop them from even subscribing: ^sqoon.*

But I continue to receive them.

Any idea on how to amend the regex or outright block them from even send subscription requests?

The list is metawiki-admins, a closed list.
