TLDR: Spam outside of swinog list by participating in mailinglist...

That is a very odd ordering of headers:

Those normally go the other way around (top one is the newest).

Nevertheless... there are two options for this kind of spam:

 - something subscribe(s|d) to the list and just spams directly
 - something parses the mailman archives and spams directly

Nothing list-admins or members could do anything about. Closing the archives is 
a silly option, closing subscriptions another silly one, why bother having a 
mailinglist in that case.
Noting that


I suggest using a mailhost that has proper spam filtering, considering it is 
trivial to identify that the sending host is not properly configured, why 
bother accepting mail from it? Then again, from the order of those headers, 
does not look like the receiver is properly configured either.
