Bad links pointing at page.
Page internally redirected (301) to new page (stupidly)
I deleted and 404'd old page and removed the 301.
Links are still appearing in Webmaster Tools after 6 months to the new page:
Via this intermediate link:http://site.com/old-404d-deleted-page/
I'm not worrying, just curious whether it's just WMT lagging behind, or if these links are still a part of the link graph used by Google?
