I must have missed this if it was ever discussed, but is it possible to mask the list members' email addresses in the archives?
I saw Mark's response and Danil's issue, but I would recommend not doing it even if available. People often do want to contact the author of a post, and sometimes the CCs, but it's not very effective in preventing spammers from harvesting.
If you control subscription and generally trust the the subscribers, then making the archives private can be moderately effective. Anonymization is more effective, but of course you completely give up the ability of subscribers to contact posters. And even then, many of those addresses you've masked are going to be available to the spammers because they're going to be in hacked address books and random S3 buckets with lax permissions and on lists that you don't run, or shared/sold by unscrupulous Internet sites.
The other thing you can do (if you're confident in your own spam filters) is to assign your subscribers addresses at your domain, and forward them on. But Gmail probably does spam filtering better. And of course your traffic will increase to a greater or lesser extent.
