Recent Mailman has a SUBSCRIBE_FORM_SECRET setting which helps but doesn't stop 
them all.

Because of these, there is now a GLOBAL_BAN_LIST, but that isn't released yet.

You want a regexp in the ban_list for each list. For the python.org lists we use


I.e., + followed by anything followed by at least 3 digits followed by @.

This has been effective so far.

The bots are doing web subscribe so there's no backscatter from this.
