Check Mailman's subscribe log? The unsubscribes and reasons should be

Members with stale bounce info can be disabled (or unsubscribed if
bounce_you_are_disabled_warnings = 0) if bounce_score_threshold is
lowered to a value <= the member's stale bounce score.

I suppose you could add to your list 'intentional action by a third
party who somehow compromised user passwords, the list admin password
or the site password or found an unknown security hole'. I don't think
this is likely, particularly the security hole.
