A robots noindex meta would work perfectly well to suppress an online bankruptcy notice about an individual.
I think this is a problem, but this is not the entirety of the right to be forgotten problem, which just makes what you proposed more efficient because people only have to contact one company with an official procedure.

> You can prevent a page from appearing in Google Search by including a noindex meta tag in the page's HTML code. When Googlebot next crawls that page, Googlebot will see the noindex meta tag and will drop that page entirely from Google Search results, regardless of whether other sites link to it.

They do say noindex overrides 3rd party links so that's something, but it's a moot point either way because this was the approach for the last decade. Having to contact each individual person in charge of each individual URL isn't even effective when the MPAA throws money+DMCA at the task, individuals asking nicely never had a chance.
