This is why I think the 'right to be forgotten' legislation might actually be a GOOD thing. Sure, it's some extra work when designing a new system, and lots of legacy systems require expensive rework, and a few twats will abuse the right to have Google redact journalistic information about their personal misadventures from the public sphere. But it's still my private data, so I should have the right to forbid companies I don't trust from storing and processing it. And they should be legally forced to oblige and have processes in place so that such request can be truly honored.
