Help:Captcha

http://hu.spam.wikia.com/images/b/bc/Wiki.png Wikia uses the ConfirmEdit extension to defend against spammers and page blanking vandals.

If a user adds a new external link (not a wiki link) to a page, they will be asked to solve a simple equation or to type in the letters they see in an image (the "captcha") before saving the page. This is to prevent automated spam bots which have been causing massive problems on some wikis.

To deter page blanking vandals, captchas are shown when an unregistered or very new users tries to blank a page.

Captchas are also shown when a user tries to create an account to prevented automated account creation by spam bots.

Registered users who have been with Wikia for four days or more should not see the captcha. If you do, please log out and back in again.

Authorised bots can be exempted from captchas. Please ask any of the Community Team if you need your editing bot flagged in this way.

For more info on captchas, see Wikipedia's definition.
