[MM3-users] Re: Recaptcha for subscription requests?

Someone suggested to me to integrate a script that checks whether a certain number of seconds has passed between visiting the page and submitting the subscription request. In the script they use, all requests made quicker are getting discarded, which seems to stop most spambots in their tracks.

But I have no idea how to integrate such a script in mailman.

P.S.: This is also becoming a pressing issue with us. It surprises me, that at this point, mailman3 doesn't seem to have any built-in support for anti spam tools.

Cheers,

Johannes
