The Librarians Wiki has a set of policies and guidelines which are expected to be followed. If a user does not follow these policies, they will be given a series of three warnings. After which, if they're violated again, said user will be blocked for a period of time, depending on the violation.
Warnings from administrators and rollbacks are not to be removed.
Badge hoarding is forbidden. Badge hoarding is when a user makes nonconstructive edits in order to receive a specific badge. Any user who does so will be blocked for a period of time.
Do not add any categories that are redundant. If it isn't made yet, it likely isn't needed, or wanted.
Unless content is terribly written, do NOT replace someone else's hard work, such as biographies. Other users took some time out of their lives to write their bio, it is completely unfair to remove their work just because you want to see your content up.
Speculation is only allowed in blogs or the forums, do not place any on articles.
