Hi.
Years ago I made a news website for a client. Now they have realized another entity has taken the styles, logo, colors (everything) and made their own website. Just another name in another city.
Maybe in my country there is nothing we can do.
If this happens to you, what would you do? (I understand laws are quite different around the world)
Not sure where you are located, but usually you can file a DMCA with Google (to exclude them from search) and file a DMCA takedown(here is how it looks on DigitalOcean) with their host as well so they shut down the site. If you do not know here the site is hosted, you can use HostingChecker to find out.
