League of Legends Wiki:Chat Moderator Policy

Kickban
When you kickban someone or, as it seems some chat moderators do, change their user group to kickbanned via Special:UserRights, you will, as per the chat policy, leave a message on the user you banned from chat's talk page with the following template  followed by your signature, the 1 will be where you put the reason they were kickbanned, the 2 will be where you put the appropriate time in accordance with the policy.

The template does not create a new section on their talk page, so you have to create a new section yourself and place the template within, make sure to keep the section title appropriate. The template will insert the following text:

Screenshots are not mandatory but are not only appreciated but also important in the case a chat ban gets questioned or opposed. Screenshots that include snippets are not acceptable, the whole chat pertaining to the incident must be captured for it to be acceptable.

Consequences
If a Chat Moderator does not follow these policies consequential action will be taken by either an admin or a bureaucrat, after consultation with another admin or bureaucrat. This action may range from a warning being issued to the Chat Moderator or the removal of Chat Moderator rights from the user with a potential wiki or chat ban. The level of action will be up to the admin or bureaucrat serving the action.
