I'm not sure what type of spam you are referring to, but when I post to this mailing list I see spamming attempts that are directly targeting my MX, without using the mailing list infrastructure. The list admins would not be able to reliably correlate which subscribed address is "A" even if I shared my mail logs.

Create a dummy mail address. Make the list server send out mails from that address very slowly at random times to the recipients. See when the spam arrives on the dummy address. Repeat as many times as needed to get sufficient correlation between spam arrival and mail distribution timepoints.
