Found the mirror of our site. I ask you to give instructions on what to do and what threatens us?

Question

Search Engine Optimization

Hello
, I discovered the mirror of our site spbteplodom.com
on a third-party resource registered on 2017.03.08,
this resource is hosted by a third-party provider ( http://www.3nt.com, UK IP address - 5.45.71.49)
When changes are made on our website, the changes occur and on the mirror.
I ask you to react and give instructions on what to do and what it threatens us with

Answer 1

If the content of the site is taken from the UK, then put the ip filter, start up only from Russia, maybe even from the target regions.
