Protect yourself against Google Proxy hack

[mrcrowley]

Thanks for sharing this bagi. I will try this for sure.
I have seen dozens of links to my site in yahoo and google from proxies though i don't know exactly how badly this effects my site.

A few proxies does not make a huge difference but when someone attacks your site via proxy attack, Google may ban or knock you off the search engines

Thanks GKD

Has anybody tried to apply this proxy hack (if thats using the right term) to a phpld directory?

I tried adding <?php include("reversedns.php"); ?> into index.php but it seems to have adverse effects of the loading of the page. If theres a chance it could slow the whole site down i would like to apply it only to the index page.

I'm not going to try it anymore untill i hear from others where they would enter the code.

Cheers!

I have it set up at The Web Directory and my site opens fine without slowing down. I have not setup the Yahoo part of the script but may do this tonight.

I added the code to index.php and show_cat.php but I don't use phpld so not sure where you need to add the code on your site - sorry

1) I just uploaded the original code which includes the yahoo code
2) Added the php include to index.php and show_cat.php
3) Uploaded

And I did not get the error message I recieved yesterday, so I guess it works.

Could you please test from Yahoo, Google and MSN please and let me know if you can see it working.

Thanks Bagi

first of all, thanks for the solution but I'm wondering whether the overhead added by the two gethostbyname and gethostbyaddr calls is needed for the average site. are there any sites that went suplemental orout of serps due to proxy duplicates?

Paul.martin when i checked my backlinks at Yahoo! Site Explorer about 5 weeks ago i had about 12 and it did affected my serps. I belive that mostly the weaker pages can be hurt with this method, but the funny guys proxified my inner pages as well. Before installing the script i had 8 pages which was not in the supplemental index, now i had 16 out of it.
