Hi,
I have reached out to the wikimania-l list admins privately with what I
found by investigating the server logs[1], it appears that the
"unsubscribe all" interface was accidentally used and then people were
silently resubscribed (so it appeared they weren't unsubscribed in the
first place).
In general, if some data loss happens please please PLEASE reach out to
the Mailman admins / SRE team as soon as possible, we have much better
tools like database backups to restore things exactly to the way they
were. Accidents happen, we understand, it's much easier for us to
intervene and reset things right after they occur rather than trying to
piece things together later.

Hi listadmins,
Many subscribers to wikimania-l received a "You have been unsubscribed
from the Wikimania-l mailing list" email today, despite the fact that we
are certainly still subscribed (and are discussing these false messages
on-list).
Has this happened with any other lists?
