I know Santorum was Google bombed, but that was an ongoing, concentrated effort by a lot of people. Yes, it's possible that for people with interesting names but boring lives could piss off someone who is going to set up an offshore site and then get Google to put it on the front page, but having to have all of those factors means it probably hasn't happened yet even once.
Actually, it's more likely that the source is in the US (i.e. Facebook, Twitter,
...). They might comply eventually, but it would remain in the search index of Google for a while.
If it's Facebook or Twitter, they both have European offices, so would probably comply fairly quickly, and something from ten years ago on either site probably wouldn't be on the first page of Google results.
Plus, if I really wanted to ruin someone's reputation, rest assured that the server I rent would be somewhere in Genericstan.
But why would Google point to your server? You are creating a ridiculous hypothetical here. You want a slanderous or insulting article based in a country unfriendly to yours on the first page of Google results. That is certainly not anywhere close to representative of the norm for these requests.
