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
^.*\+.*\d{3,}@
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.
