reCAPTCHA MediaWiki Extension
use scanned parts from books as captchas
Extension:ConfirmEdit - MediaWiki
a very simple text Captcha that will probably catch most bots. It was designed after MediaWiki 1.5, largely by Brion VIBBER. The FancyCaptcha addon extension creates more complex image captchas.
reCAPTCHA MediaWiki Extension
a MediaWiki plugin that uses a CAPTCHA to prevent spam.
Extension:ConfirmEdit - MediaWiki
Two captcha implementations for MediaWiki, one that is a simple arithmatic problem, the other is based on identifying generated images.
Extension:ReCAPTCHA - MediaWiki
A more complicated captcha where people identify words that failed OCR. Identifying the words helps a library digitization project. There is also an audio version of the captcha for the visually impaired.

Lenz Grimmer: Fighting spam: reCAPTCHA installed on the MySQL Forge Wiki
Today, I again spent about an hour to revert changes made by spambots on various MySQL Forge Wiki pages. As I was really sick of this, I now installed a new plugin: reCAPTCHA - this will hopefully raise the bar for spambots to create new user accounts automatically for spamming the Wiki. If you are a registered user already, you will probably not notice the change - by default, CAPTCHAs are only displayed on the following events:
- New user registration
- Anonymous edits that contain new external links
- Brute-force password cracking
