Confluence 4.0 : Configuring Captcha for Spam Prevention
This page last changed on Apr 18, 2011 by pwatson.
If your Confluence site is open to the public you may find that automated spam is being added, in the form of comments or new pages. You can configure Confluence to deter automated spam by asking users to prove that they are human before they are allowed to:
Captcha is the technical term for a test that can distinguish a human being from an automated agent such as a web spider or robot. You can read more about Captcha on Wikipedia. When Captcha is switched on, users will need to recognise a distorted picture of a word, and must type the word into a text field. This is easy for humans to do, but very difficult for computers.
You can configure Confluence to enforce Captcha for certain types of users. You can exempt logged-in users (they will have completed a Captcha when they signed up) or members of particular groups. By default, Captcha for spam prevention is disabled. If you enable it, the default is that Captcha for spam prevention will apply to anonymous users only. Only anonymous users will have to perform the Captcha test when creating comments or editing pages. Captcha images will not be shown to logged-in users. To enable Captcha for spam prevention in Confluence:
