> Google doesn't index most moderated forums either. They've always been walled gardens to avoid bad behaviors. forums don't necessarily need to block search engine crawlers to prevent bad behavior, that would most likely be done with restrictions on account registration or limitation on what new users can post (one forum I am on hides posts from new account until they've been reviewed by a mod)
