How to use JavaScript or/and PHP, to detect a website/page being stolen/cloned and then redirect reader back to my website

Question

I found hundreds of cloned versions of my website.

Whoever is doing that are using some code that clones my web pages, changes my website name mydomain.com to clone1.com, clone2.com, clone3.com etc and this makes it impossible to use a simple JS or PHP to check if the header URL is = to mysite.com then redirect.

It also does not work using the .htaccess

For this reason I have created this code:

<script type="text/javascript">
if (window.location.href== "http://clone1.com/cat1/{{{ $title->id }}}-{{ (Str::slug($title->title)) }}/cat2/{{ $se->n }}/cat3/{{ $episode->ep_n }}") 
{
   window.location.href = 'http://google.com/'; 
}
</script>

This script completes its purpose but is too long and is also very restrictive because it must contain the exact URL.

I'm looking to do this:

<script type="text/javascript">
    if (window.location.href== "http://
//contains this part in its URL
clone1.com , clone2.com , clone3.com , clone4.... 
}}") 
    {
       window.location.href = 'http://google.com/'; 
    }
    </script>

How can I create a global JS (JavaScript), that would detect if the current page is not on my domain and then redirect the reader to my domain and the same page?

Many thanks

1. Best Solution - Early Detection

Depending on your main traffic source, it is possible to detect who is scrapping you and block them based on their IP, Headers, number of page views and other data, using PHP & HTACCESS.

I really like this answer on the StackOverflow, that discusses almost all the options available for early detection.

How to detect fake users ( crawlers ) and cURL

2. Plugins & Extensions for Open Source Content Management Systems

Wordpress

If using Wordpress CMS, you can try some plugins, like WordFence, that can detect and block fake Google Crawlers, block based on the number of page views etc.

Other CMS

If you can't find a similar solution for your CMS of choice, consider to ask a community for a help with creating the solution like that, as I believe many people could benefit from it.

3. Solution for already stolen content with JavaScript

Sometimes the easiest road to hide something in JS, is to actually HIDE something by OBFUSCATING and by hiding in multiple important files. For example, obfuscate some important file on your website without which the website just wouldn't work properly.

For example, put an obfuscated version of the code below somewhere in JS file in the header, Obfuscate this code using any free services online or download your own library on Github:

Non-Obfuscated:

w='mysite.com'; // Current URL e.g. 'mysite.com/category1/page2/'
function check_origin(){   
   var check = 587;
   if(window.location.hostname != w){
       window.location.href = w;
   }
   return check;
}
var check = check_origin();

Obfuscated example:

var _0x303e=["\x6D\x79\x73\x69\x74\x65\x2E\x63\x6F\x6D","\x68\x6F\x73\x74\x6E\x61\x6D\x65","\x6C\x6F\x63\x61\x74\x69\x6F\x6E","\x68\x72\x65\x66"];w= _0x303e[0];function check_origin(){var check=587;if(window[_0x303e[2]][_0x303e[1]]!= w){window[_0x303e[2]][_0x303e[3]]= w};return check}var check=check_origin()

Now put an additional code in some Footer JS File, to verify the code above wasn't modified in any way:

Non-Obfuscated example:

 if(w!=='mysite.com'||check == false || typeof check == 'undefined' || check !== 587 ){
    window.location.href = 'mysite.com';
}

Obfuscated:

var _0x92bb=["\x6D\x79\x73\x69\x74\x65\x2E\x63\x6F\x6D","\x75\x6E\x64\x65\x66\x69\x6E\x65\x64","\x68\x72\x65\x66","\x6C\x6F\x63\x61\x74\x69\x6F\x6E"];if(w!== _0x92bb[0]|| check== false||  typeof check== _0x92bb[1]|| check!== 587){window[_0x92bb[3]][_0x92bb[2]]= _0x92bb[0]}

I have used free online service from Google's search results for the term "Free Online JS Obfuscator:

4. Fight thieves with available methods e.g. Request a Ban from Search Engines – The Digital Millennium Copyright Act of 1998

Here is a blog-post that describes what to do when someone is stealing your content.

https://lorelle.wordpress.com/2006/04/10/what-do-you-do-when-someone-steals-your-content/

You can investigate who is doing that and report them to their partners, search engines, advertisers - to disrupt their business.

Depending on their country of origin and yours, it is maybe even possible to sue them and win.
