Help:Criteria for deletion
Deletion of a page or file requires a consensus decision by the users of the wiki. It should be requested via the talk page, (remember to sign your posts with -- ~~~~). The page creator and any major contributors should be notified. Before nominating a page for deletion consider whether it can instead be improved.
Otherwise reasons for a deletion request (via the {{Del}} template), can be because the only author of the page requests it, the page is spam or vandalism, is unambiguous copyright infringement, the file is redundant or corrupted, etc.
