I started a couple of threads on this so far as the redirect page hi-jacking issue is costing me a significant amount of my income.
I am interested in What people have done and what effect, if any, it had. We all now know the extent of the problem so plz only post if you have something meaningful to add.
The first attempt i did was to stop the hijacking by getting the offending site to remove the link. But will not remove the link as the hijacking is performed by software packages (in this case dont even know how to remove the link.)
The second attempt was to use Googles URL removal console but as the sites causing the problem are not mine this is not possible.
The third attempt is to make all links on the page absolute. This is in the hope that even with the home page hijacked i might be able to get other pages listed. I am yet to see results of this but i would like to know if anyone else has tried it.
The next attempt will be to use robots.txt to block my home page and reinclude it after it gets dropped. However as the redirecting pages dont use robots i am not sure this will work.
I have made many of the links on my site absolulte some years ago, I.e. I use www.example.com/path/file.html instead of path/file.html or even file.html for pages in the same directory.
Having absolute links helped me in the following way:
If visitors click on links on hijacked pages, they go to your site, so you get back some traffic
Many content copiers don't change the source. Therefore the absolute links to your image files remain there. These links from other sites to your images are easy to find so you can use your server log to find sites that copied your content.
Absolute links to files on your site are an easy prove that the other site copied your content and you didn't copy theirs. I have used this argument a few times in DMCA complains I sent to ISP's with very good results. (Removal of offending pages withing 24 hours in all cases)
I had my Attorney send out cease and desist notices to the parties responsible for the 302's. It is his opinion that as owner of my domain, I have the right to oversee how and where it is used. Another site benefiting from the use of my URL in this manner is, in my opinion, unfair use of my URL, and as such I have the right to have it removed.
The theory that they aren't copying anything from your site does not apply, here. The URL is hard coded somewhere on their server, and that is unfair use. They were advised to remove the URL within 24 hours or further legal action would be taken.
So far, everyone except for one has found a way to remove the links to my site. The one who didn't also had copied a large part from a page on my site. I filed a DMCA complaint, and that site has now been taken down. I think the fact that the messages came from an Attorney helped considerably.
It's a continuing cycle, you have to contact them and tell them to remove the link(s). Temporary fix, perhaps, but it's better than doing nothing which is the only other option I've heard at this point.
