in apache 2.4 you would do

    <LimitExcept PUT>
      Require all denied
    Require all granted

but how does this help? No one, including bots GETs the subscribe CGI,
and subscription is via POST, not PUT.

The scenario is the same for bots and humans. GET the listinfo CGI with
the hidden token and then POST the form to the subscribe CGI. I don't
see how you can block one without blocking the other.
