MediaWiki:Captchahelp-text

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.

Sometimes, especially when adding new web links to a page, the wiki may ask you a simple question. This will allow real humans to make their posts, but because the questions are specific to this website, it will (hopefully) stop most spammers and other robotic attackers who tend to carpet bomb many websites with spam all at once.

Please contact the Sysadmin team for assistance if this is unexpectedly preventing you from making legitimate posts.
