My question is - are spamers able to pick up lists from the default (but not easily accessible) default mailman listinfo page and start bombarding us with spam on all lists?
Yes.
Or should I set the "Advertise
this list" option to "no" for the lists on the default listinfo page?
That would be your choice. But anything that is publicly accessible is game for being snarfed by spammers.
There are tools that use this fact to their advantage against spammers, by creating bogus e-mail addresses as part of a "honeypot" campaign, where they know that each address they generate is unique and they know all the details of which IP address was scanning their system at what time when they generated that address, and if anyone ever tries to send anything to that address not only are they automatically blacklisted but so is the IP address that did the original scan, and so on.
However, this doesn't help you if you're just trying to run some mailing lists for your customers or your community.
