There are very few policies which apply across all Fandom wikis. These can be found on Fandom Community Central at Category:Policy.
The Disney Infinity Wiki is intended to be an information source for all things directly contained within or related to the Disney Infinity products. Other content, such as in-depth character and movie background information, is better left to those Fandom wikis that already cover such content. See:
As Disney Infinity was published with an ESRB rating of E10+, all content on the Disney Infinity Wiki is expected to comply with that. While Fandom may choose to disallow accounts for children under 13, it doesn't prevent the site from being accessed or viewed by same. With regard to language/profanity, if it isn't in the game, it isn't allowed here.
Policy enforcement is at the discretion of the administrators; violations may be subject to "disciplinary action, up to and including a permanent ban from DIW".
