Apparently they got it from archive.org. They made no changes to the page except to throw in some links, fitting them into the context so it will look natural to a crawler. They neglected to remove the visitor counter, that's how I found out.
They even left the copyright notice I had on the page.
They're using my images, my design, my content, my js, etc. Even though I no longer own the domain of the original site, I seem to be last owner.
Can't find out who owns the domain so I guess I would go through the host to get in touch.
Wondering if there is any legal remedy for this.
