[Description] Adding very large (measured by the number of bytes) amounts of bad-faith content to a page so as to make the page's load time abnormally long or even make the page impossible to load on some computers without the browser or machine crashing. Adding large amounts of good-faith content is not vandalism, though prior to doing so, one should consider if splitting a long page may be appropriate (see Wikipedia:Article size). [Type]
