My wiki has been overrun by spambots. Thankfully because of this extension, these spambots are not able to edit the pages, but they are still able to create an account - about 50 new accounts everyday.
How can I change the CAPTCHA settings to stop these spambots? I use the question CAPTCHA - it is the easiest to use and install and I want to keep it without adding new CAPTCHAs.
Is there another extension I can add which will limit the spambots creating a new account?
These bots only create new user pages - can I block all users from adding external links - but only to user pages?
Thank you.
Update:
