Easy way to integrate captcha/reduce subscription spam?
Dear all,
my mailman3 instance is flooded with subscription spam, yet I haven't found any canonical method of integrating a captcha in to the subscription form. Is there really none at all? Perplexity.ai says I should install the python package django-simple-captcha but is unclear about the steps needed to actually make the captcha appear.
Are there other ways? Is there any method that is robust and survives upgrades?
Also, would there be a way of batch-deleting all those thousands of spam registrations that have accumulated (what they have in common is that their email is unconfirmed)
Thanks in advance for any suggestion!
Johannes
Dear all,
sorry for repeating my question, but the degree to which my instance is now being flooded by spambot registrations is truly annoying. Mark's clean_user.py script reliably deletes most of those accounts, but it would be great if we could prevent them from being created in the first place. In Mailman2, this was relatively straightforward. Is there anyone who has successfully integrated some piece of code that stops those spambots in their tracks?
Thanks!

The Recaptcha debate has happened before and there was a good reason given by the Developers why they aren't keen on it. You can search the archives for that. Fedora (or someone using it) patched their Mailman3 to have Recaptcha: https://github.com/pbiering/mailman3-rpm Maybe you are brave enough to patch yours.

Thanks so much! Blocking Tor seems to make a difference
Cheers,
