Is this a ban?

Lost my website name in SERPS

[moftary]

Greetings,

I have a website that is bluh bluh dot com, and since no one else is using that bluh bluh for its website now I was ranked #1 for bluh bluh. (sorry for bluh bluhing too much but its the forum rules and my bad english as well).

Suddenly when I now search for bluh bluh I cannot find my website anywhere in SERPS. It still have its PR untouched and the inner pages are still there for the same keywords. Even the same traffic. Is this a future ban? Should I be worried? Why is so?

Cheers,
