Anyone can request unsubscription for anyone else via the user options
login page or via a spoofed From: in an email to list-leave or
list-unsubscribe or an unsubscribe command to list-request. One can
also request unsubscribe for another via a "unsubscribe address=xxx"
command to list-request.

Most of these pretty much have to be intentional, but if you have a
personalized list with a footer similar to the

Unsubscribe:
http://mail.python.org/mailman/options/mailman-users/user%40example.com

footer added to messages from this list, it is possible that your list
member forwarded a list message containing that link to someone else,
and the recipient followed the link and clicked "Unsubscribe" thinking
she was unsubscribing herself from a list.
