like other online communities, e2 has a social hierarchy and code of behavior, to which it is sometimes difficult for a newcomer to adjust. moreover, some people complain that new users are held to a different standard from established contributors, and that their writeups are singled out for deletion regardless of content. another complaint is that all too often, site administrators remove articles that they do not agree with or which they do not see explicit value in, thus biasing the content of the database. others dismiss such complaints as unjustified; they observe that few communities treat newcomers exactly like long-time members, and they claim that those who learn and obey the rules are usually—though not always—treated fairly.
