Greetings all! Since yesterday NWR-Hist mailing list is getting different spam emails. All of them was held automatically and users were blocked afterwards but the number of this mails doesnt't look good: we've got 6 so far, and one of them was literal scam mail pretending to be some Wikimedia staff mail about spam problem (but with fake lookalike address). Do I have to do something except that I've done already? Or should I notice someone in WMF?
