I believe it is impossible unless you are a good hacker(and I know there are some good hackers out there), but I thought I would ask the question. If you posted something on a Usenet group 20 years ago, and you don’t have your user id and password anymore, how can you delete the posting without getting a court order to prove who you are and that you posted it 20 years ago. The webmaster for this Usenet group doesn’t exist anymore. I was surprised to see the Google search engine actually be able to pull up stuff for the Usenet groups from 20 years ago. If this is not possible, then my question instead is, how can you trick the Google search engine to alter something from coming up on the first page of Google, to coming up on the 3 or 4 page in the Google search engine? I’m sure there are tricks on how to do this?
