Greylisting
To guard against WikiSpam, each URL that is added to a public wiki by a non-authenticated user is added to the "greylist". This list contains URLs and their authors.
All URLs that are on the greylist are rendered differently from other URLs:
- The <a > tag has a rel="nofollow" attribute to instruct spiders not to follow the link
- When the user clicks on the link, the browser has to go through the redirection script, so that spiders don't see the actual URL being pointed to
The greylist is stored in the ConfigDirectory and can be edited from the AdministrationPages
When an URL is on the greylist, the administrator can take one of two actions:
- Accept the URL. The URL is removed from the greylist and will be rendered normally. You may want to RegenerateSite to re-render the URL.
- BlackList the user and URL. The user and blacklist are no longer allowed on the site. All edits by the author are removed.
