Some bad person is masking my website with his domain www.baddomain.com. I would like to block it somehow from my nginx
config file if that is possible.
I tried to see from "baddomain.com" source code if he is using URL frame, but can't find one. Also domain extensions are being duplicated on every page.
I have filled Copyright Claim with his domain issuer but that could be long process or useless.
I own "original.com" but he owns "baddomain.com". I don't want google to think there is duplicate content with my site.
How could I block masking url from Ninx? I use DigitalOcean droplet, Ruby on Rails. Unicorn and Nginx for server!
