There are some people who abuse the system (who I hope you identify), and also some people who really should have the right to be forgotten.
As far as I can tell, using a US based VPN/proxy does not censor results - at least, it does not show the message.
Therefore, you just need to cross-reference the results from different geographic regions. However, it will be difficult to tell whether a certain result is missing due to censorship, or the fact that result rankings are slightly different for different countries.
Once you find a "suspicious" result, I guess you could try searching direct quotes from the article - If it doesn't show up in those results, then it's probably censored.
This process will need to be automated, if you want to check every name.
