Someone has created an exact copy of my site.
At first, the code of his pages were identical to mine. A few days later he just replaced my internal links with the same links to his own domain. At the top of his source code he uses some "Vodafone securenet" script connecting to my site.
At first I thought he was using embed or iframes or something to reproduce my site, but I have posted a new post and it doesn't show on his domain.
I have contacted the company that protects his whois info and I plan to issue a dmca with Google.
What else can I do?
Btw, this is obviously a neg seo case, since his site has no chance to appear on the search, yet it can hurt mine as duplicate content.
