Not sure if there's any more recent version of that page.
The top of the list is http://news.bbc.co.uk/1/hi/magazine/6965657.stm; presumably any of the people mentioned, including in the comments, might be responsible for the right-to-be-forgotten request to Google.
What's more curious, to me, is that several of the BBC's list are references to a series of articles on 3 students, eg http://news.bbc.co.uk/1/hi/education/3500850.stm.
Now if you Google any of those 3 students, https://www.google.co.uk/search?q=site%3Abbc.co.uk+"nikki+ho... then that page, that BBC say is hidden in Google SERPs, appears?? Did someone mess up. Google does say "Some results may have been removed under data protection law in Europe.", however.
Similarly, this page http://news.bbc.co.uk/1/hi/england/wiltshire/4747988.stm is listed on that BBC page, but searching the main name and "BBC" brings up that same page as the first result; again the "Some results may have been removed [...]" text is given.
I think some of us that have had the foresight to prevent such things as in the OP from ever possibly being an issue in our lives might forget the rational decisions made in ignorance or a moment of exuberance (i.e haste).
Still, the internet is global and laws are regional, so ineffective legislation is a waste of time.
[Not going to get into P2P tech that is still un-censorable]
I hesitated, the BBC page will be an ocean of views compared to the puddle of view this thread gets ... I didn't follow the details for other posts, concerning crimes. The cited post looks like it was probably to hide what's essentially normal student behaviours (though one can't be sure). At least there's nothing intrinsic that seems worthy of censoring.
What it does shine a light on for me is how very bland information about us that we share might become a source of regret later in life.
