What happens when I post content as "A Yahoo!7 Contributor"?
If you chose this option, available on some Yahoo!7 sites, you can post publicly anonymous content. Your display name and image will not appear with your post, and the content will not be publicly associated with you, but Yahoo! will still know your identity.
If you choose "A Yahoo!7 Contributor," the identification applies only to a specific post; it does not become your new display name. For instance, if you have 10 restaurant reviews in Yahoo! Local and you sign one of them as "A Yahoo!7 Contributor," just that one review is posted as publicly anonymous content.
