Track and delete all copies

Anything that's posted online may be available long after you've deleted it from the original source. That's because search engines and other web crawlers move around the internet indexing websites and making copies. Some sites reprocess online content without your knowing about it. So just because you delete something, it may still be available on the internet somewhere. A software that tracks your postings and deletes not just the original but all copies of it on the web would be very useful. You never know when you might post something you want to delete later.
