 ### The Big Guns
 
 My first reaction was to go and look for a way to add a CAPTCHA to the
-subscription page.  Unfortunately, Mailman itself does not support a CAPTCHA (at
-least not Mailman 2), and the existing patches I found were all about adding
-support for Google's reCAPTCHA.  I am not going to expose my users to Google's
-tracking like that, nor am I willing to actively discriminate against people not
-having Google accounts (reCAPTCHA is much more annoying if Google can't track
-you because you are not logged in), so reCAPTCHA was clearly not an option.

 The more people do this, the more it will help to stop this kind of spam.  Or
 rather, it'll force the spammers to upgrade their game.  I assume eventually I
 *will* have to add a CAPTCHA.  Or maybe there is a simple and reliable way to
-migrate to Mailman 3 before that happens---and maybe that will have a CAPTCHA.
