Our ever-innovative friends the spammers have discovered subscribing to Mailman lists. We got one spam posted to wikien-l from a subscribed address today. It got caught in the mod queue, but nevertheless ...
Is this a well-known phenomenon? Is there anything like captchas in Mailman to avert this sort of thing?

Oh it happens every once in a while.
Alas googling "mailman captcha" turns up mentions of captchas on every mailing list on the net. ;) I'd be surprised if someone hasn't already done it, but we could probably hack one in if necessary.

This is a sole example so far. Probably wouldn't bother yet :-)

Now, this post makes the first result ;) Those susbscriptions should be stopped by the mailman challenge, and to pass it they should use real addresses, so at filterable. It *would* be a problem if they used addresses of subscribed members, as not everybody has SPF. I'm more concerned about mailman way of publishing email addresses, too easy to harvest by bots.

I'm not sure how a captcha would help. Is there any reason to believe the message was even sent by a bot?
