[solved] Captcha on registration page? Auto-delete user without e-mail confirmation?
Since I postet the first links to my wiki running on tiki, I get random user registrations which use (presumably) auto-generated e-mails. They mostly never get confirmed and stay in the user list as orphans.
Best solution would be to completely prevent crawlers to register. This could be done using a captcha. How do I do that?
If that s not possible, I at least want to automatically delete users who never confirmed their e-mail. That would at least get rid of most of the orphans.
I am using tiki 21 LTS.
Referer Validation is active. I just activated e-mail validation using deep mx-search. I will see how effective this is in a few days. Before I did not validate the e-mail at all.
