MediaWiki:Captchahelp-text

From Wikipedia, the free encyclopedia

Explanation

Web sites that accept postings from the public, like this wiki, are often abused by spammers who use automated tools to post their links to many sites. While these spam links can be removed, they are a significant nuisance. A common counter-measure is to show the user an image of colored or distorted text, known as a CAPTCHA, and ask them to type the words shown. Since answering a CAPTCHA is a task that is hard to automate, it will allow most real humans to proceed and publish their posts while stopping most spammers and other robotic attackers from being able to do so.

On Wikipedia, you may be asked to fill in a CAPTCHA when adding new web links to a page, when you attempt to create a new account, or when you enter your password incorrectly. Unfortunately, this may inconvenience users with limited vision or using text-based or speech-based browsers. We do not have an audio alternative available at this time.
