FWIW, this is not the first time an admin mistakenly has done this. It is an issue in the interface that doesn't even ask for confirmation before mass unsubscribing everyone.
There was a task for it but I can't find it, if anyone remembers please send it to me.

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?
