Page dropped from TOP position to very end of search results

On this page [webmasterworld.com ] I found somebody [asamuel] who has the same problem that I have, but the thread is closed, so I'd like to start a new one here.

My site has been on google since june and then at the end of september, it just fell off its top spot for a certain keyword and is now nowhere to be found other keywords have also dropped. It has been crawled but googlebot, so I cant fathom why it has not come back yet?

on my site i have the exact same problem, but i noticed that i still can be found in google's index for the same search queries as before, but now i'm at the very end of all search results mostly. for words that i was on TOP with before, i'm on the last page of search results now.

i also noticed that when i've been found through google with search queries, and was among the about top 20 results for the word when i was found, i suddenly drop back to the very end of all search results, somewhere between 800 and 900 of all results at times.

i do not understand what's happened to my site. i find my content now listed at the end of all search results, among porn pages, while my page is by far not a porn page.

could you please tel me what's happened to my listing and what i can do to resolve the problem?
