I've come across a deleted answer that is obvious spam: it's nothing more than a link to a site selling high-end purses. The answer has been deleted, but it's still visible to me as a 10k user. It makes me mildly nervous to have a link to a suspicious site sitting there where I might accidentally click on it. (Usually I've got pretty good aim with a mouse, but I have made mistakes before.)
What is SE's policy here? Do the mods have a readily-available mechanism for purging posts from view of 10k users? Note that this answer dates back to August 2010, so I understand that any such mechanism -- if it exists today -- might not have existed back then. Maybe more recent spam-handling procedure prevents this from happening?
Also, is there a verb to describe such an action? The best I can think to use is "obliterate", "super-delete", or "delete it harder".
