Wikipedia:What happens on other wikis stays on other wikis

When writing about other wiki sites in article space, it is important to maintain a neutral point of view. When members from one site encounter members from another, potentially competing or rival site, they should remember to leave their prejudices outside and not argue about politics on Wikipedia. It may also be wise to avoid criticizing other wikis on userpages as it tarnishes Wikipedia's reputation. Especially do not encourage vandalism at any wiki; such behavior may result in a block. Remember, Wikipedia is not a web host.
