Google shouldn't have to make intelligent decisions as to what needs to be removed. It should all be automatic. Either everything is removed, or nothing is removed. Only by court orders otherwise.
So I should be able to request that searches for "microsoft" should not go to "microsoft.com"? And Google should be forced to honour that?
Those people, who want to be forgotten, should go after those hosting the material, not the search engine pointing.
The reason that going via the search engine works, is that it is possible. Many content platforms don't have easy mechanisms for identifying and removing content, and many are hosted abroad (whereas Google is active in the EU and can therefore be instructed by EU authorities). Slashdot, for instance, has only ever removed comment content once to my knowledge and they made a huge deal over it. Search engines, however, have enough layers of indirection between the search box and the results that adding a rule to exclude certain results from certain keywords isn't all that difficult.
I don't think that the "right to be forgotten" is a good idea. But saying "Instead of doing it via a route that is possible, they should do it via a route that is impossible" isn't a helpful contribution. Just say it's a bad idea, rather than suggesting an impossible course of action.
