From Nookipedia, the Animal Crossing wiki
Honored members are a special group of users that have been recognized for making a significant contribution to the wiki. Users in this group, like the autoconfirmed user group, are maintained by the MediaWiki system. A list of all honored members, past and present, can be found on this page.
Qualifications and benefits
The current qualifications to become an honored member are to make 150 quality edits within a 30 day period. Doing so will earn you honored member status for the same number of days. During this time, ads will not be displayed while browsing Nookipedia. You will also earn a permanent spot on the list of honored members. This is our way of thanking you for making Nookipedia the best Animal Crossing resource on the internet.
At the request of a bureaucrat, any user may be made an honored member if they have made a contribution that deserves recognition. Whether or not that user will be publicly recognized on the list of honored members will depend on the quality and quantity of the user's edits at the time of nomination.
If a user is found to have spammed edits in order to achieve an honored membership, their privileges can and will be revoked. Additionally, further action may be taken against the account at the discretion of the administrative team.
