Spam Prevention via Captcha

All Versions

Confluence 3.0 Documentation

Index

You need to be a Confluence administrator to enable Captcha.

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:

  • Sign up for an account
  • Add a comment
  • Create a page
  • Edit a page

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.

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 images will not be shown to logged-in users. Only anonymous users will have to perform the Captcha test when creating comments or editing pages.

To enable Captcha for Confluence,

  1. Go to the Confluence 'Administration Console'. To do this:

    • Open the 'Browse' menu and select 'Confluence Admin'. The 'Administration Console' view will open.
  2. Select Spam Configuration' from the 'Configuration' menu on the left.
  3. Turn on Captcha by clicking the 'ON' link.
  4. If you want to disable Captcha for certain groups:
    • Select 'No one' if you want everyone to see Captchas.
    • Select 'Signed in users' if you want only anonymous users to see Captchas.
    • If you want everyone to see Captchas except members of specific groups, select the 'Members of the following groups' and enter the group names in the text box.
      You can click the magnifying-glass icon to search for groups. Search for all or part of a group name and click the 'Select Groups' button to add one or more groups to the list.
    • To remove a group from the list, delete the group name.
  5. Click the 'Save' button.

    The captcha on confluence.atlassian.com does not work for me on Firefox 3.0.7, but works well with IE 6.0.
    It displays the image with the word correctly, but doesn't accept my answer. Tried many times...

    Is there something wrong with my Firefox?

      Hi Dominik,

      I did not encounter such an issue on my Firefox. Perhaps, you can try creating another profile for your Firefox - this will allow you to start fresh without extensions, themes. etc.

      Cheers,
      Azwandi
