Have you sent a DMCA to Google asking them to remove their Search Engine cache of the AppSpot page?
I did, and it was denied, because it was a "proxy".
So, I put in some .htaccess rules to block AppSpot's user-agent, then used the public url removal tool.
Did it work? Yes. However, I disagree with proxies getting an exception. This method only worked because the python api in appspot doesn't allow code to alter the user-agent.
To me, if you're going to run one of these "web proxy" sites, you need to either keep proxied content from being indexed, or you should be held to the same DMCA rules as everyone else. I see you disagree...that's fine.
Once this negative seo technique spreads to other places...places where they can alter the user-agent, I won't have that option.
