Both G! and Y! are resistant when indexing pages if backlinks are poor. Bot some ancient pages are never erased. All backlinks disappear, and page itself disappears, but cache remains there forever. I know why such pages are never erased. Page has extremely low support, so SE waits for a very long time before deciding to visit the page again. Since this waiting time is amost infinite, PR -3 pages are never erased. if there are confidential data there it can be used against you. You can get them removed from G! but it takes time and other SEs may not allow 24h removal service. Any solution?
