From Citizendium, the Citizens' Compendium
The Citizendium is committed to maintaining your privacy.
For contributors, however, we realize that privacy is a special concern, since we require the use of real names and identities. We require that contributors reveal this information, so that our readers, and your co-authors and co-editors, know who you are and that there are people who are willing to take real-world responsibility for what appears here. We believe that this is the only way to have a mature, pleasant community and a credible product. We are a community of real people, not avatars and pseudonyms.
Still, you need not reveal very much information about yourself. When you join, the only information we will put on your user page biography is what you say we may put there. After your user page is created, you may edit it yourself, as long as you continue to maintain some helpful information about your interests and education.
Your name should not show up in well-behaved search engine results, such as those of Google and Yahoo!, because of your Citizendium account. This is because we indicate they should not spider Citizendium userpages and talkpages with robots.txt (see robotstxt.org for information). However, certain external sites that copy content from Citizendium under its license may not adhere to our indexing rules. Consequently, copies of user and talk pages appearing on those sites may be indexed.
It is impossible for the vast majority of contributors or readers to find out anything about you other than through what you yourself reveal, through your participation in the system. A category of contributor, called "Constables," who keep our global village here running smoothly, do have access to your e-mail address and any application details. The details of editor applications, moreover, are accessible by "Editorial Personnel Administrators." These people are chosen for their responsibility and maturity, and they are intelligent and sensitive to privacy concerns. They know not to share your personal information.
