Hi there.
On the lists "wikimedia-sk" and "wikimedia-sk-oznamy", where I am admin, we
have received suspicious mass subscriptions (several tens in several
hours). They came from nowhere, all with @aol.com address (very unusual for
our target group) and all declared only first name. Most certainly some bot.
Provisionally I have set them all for moderation. Eventually I could block
subscriptions from @aol.com addresses (no too big deal, because hardly
someone real in our audience is using them) but I prefer systemic solutions
and not to cure symptoms. And possibly someone else here is running into
the same problem.
Any suggestions?
Regards!
