I can't speak for doing it globally but on your own lists you can go to the Subscription rules (under privacy options) and add "^.*$" (no quotes, this bans "everything") to a new line under List of addresses which are banned from membership in this mailing list (the 'ban_list'). It will also ban you from adding people manually but you can temporarily remove it and add back. I've done this on a couple lists I moderate which didn't generally accept new subscriptions anyway atm and has stopped the spam.

Hi All,

Many of you would have noticed that now we have started getting additional subscriptions from email addresses with yahoo.com domain, while aol.com continues.

I would like to know and propose whether it is possible to suspend subscription to all wikimedia mailing lists, or at least those affected by this swathe.
I'd support this, as long as some sort of feedback is provided during the blocked subscription attempts.  As you say, I'm very worried that I'm overlooking legitimate subscription requests to the lists I administrate because they're lost in the chaff of this attack.


I would prefer subscriptions suspended to my mailing list instead of getting these 100s of dodgy subscription as there is a high possibility of us missing genuine subscription request among these several hundred spam ones.

Regards,
Dhaval Vyas
