HELP. Has my 9/11 site been hacked?

I have a site

http://adap2k.freeservers.com

When you search for the word "adap2k" on google.
as I do every so often, the header or title has been
changed from its original. It use to read:

"WORLD TRADE CENTER COVERAGE"

Now it reads: "GET YOUR DOMAIN: .com .net .org .biz .info "

This change seems only on particular pages incluiding the front.

Have I been hacked?
