How can I delete an archived page?
Write to webmaster@archive.is
Currently there is no automated way to do it.
And it is not so easy to implement as it might look, because a lot of archived pages are referenced from Wikipedia or other wikis. The deleting of a page should be somehow synchronized with fixing those references on the wikis. Otherwise, if would be ridiculous if the site which goal is to fight the dead link problem has dead links itself.
