       | Leaving aside the morality, one huge objection to this level of
       | targeting granularity is that it's just _bad business_.
       | 
       | Obviously a gross oversimplification, but to a first
       | approximation ads ranking, pacing, and auction drive ads revenue.
       | Ads targeting drives _careers_ , at least at FB at least as of a
       | few years ago.
       | 
       | The creepy factor does _way_ more damage to FB's business than
       | the bells and whistles that the buyers of inventory use adds to
       | it.
       | 
       | When something happens on Google, people feel like it happened in
       | their living room. When something happens on FB, people feel like
       | it happened in their _bedroom_.

         | Facebook and other ad platforms are just milking the cash cow
         | as much as possible until it is not no longer possible because
         | of regulation.
         | 
         | However, regardless of privacy laws and other issues with
         | advertising, this particular kind of abuse could be prevented
         | by displaying how many people fall into that ad's targeting
         | criteria and how much this advertiser has spent in the last
         | year. Legitimate ads will typically target a large amount of
         | people and would've spent significant amounts, where as
         | "gaslighting" ads like these would typically reach very few
         | people and the advertiser would've spent a relatively low
         | amount in comparison.

         | Facebook incited a genocide in Myanmar. PR is not in their list
         | of worries.

         | They helped to create a genocide in Burma. If people didn't
         | leave after that then I doubt any "creep factor" is going to
         | hurt their business.

       | This was famously used to target Jeremy Corbyn.

       | Labour staffers working to prevent their own party winning under

       | able to use geofencing and other specifiers so it looked like

         | Yeah like 7 years ago I was thinking about moving into a
         | marketing role and bought a book on social media. The
         | introduction included a bit where the author bought a Facebook
         | ad wishing his wife a happy anniversary because he could target
         | her so precisely.

       | It's so frustrating that our political institutions, who are
       | supposed to act for our collective benefit, are so incredibly
       | useless.
       | 
       | We've known unambiguously about the impact big business had had
       | on our climate, yet it took decades for governments to act
       | decisively - mine still hasn't.
       | 
       | We knew about the hazards of smoking for decades before
       | government acted decisively, despite the enormous costs to
       | society. In many cases these companies continue to be allowed to
       | sell their shit, despite knowing that it's not just addictive,
       | but also toxic.
       | 
       | Asbestos, leaded fuel, road safety, and many other large problems
       | were left unregulated for _decades_ , and in all cases a small
       | number of corporations profited - often marginally - at the
       | expense of thousands or even millions of individuals.
       | 
       | And now we see the same with Facebook. We've known for more than
       | a decade that Facebook is a toxic waste pit of information.
       | 
       | There is much that could be done, and much more quickly, but our
       | politicians sit on their fat arses and do Jack shit.
       | 
       | Without _effective_ democracy we have no way to resolve these
       | problems because the whole reason we have a democracy in the
       | first place is to ensure these powerful bastards work in the best
       | interest of _everyone_.
       | 
       | If King Zuckerberg is more powerful than his parliament of
       | lapdogs, then democracy is dead.

       | Serious question:
       | 
       | While you can target a SINGLE person, the targeting doesn't tell
       | you who that person is. So, I can target my wife - but I already
       | knew who she was. Also, I can target someone using 18 parameters,
       | but I don't actually know who that person is unless they click on
       | my add and tell me "this is who I am".
       | 
       | So: does this violate privacy laws?

         | Maybe. I'm not a lawyer, but it's unlikely that you make your
         | friends sign NDA's to prevent them from selling metadata about
         | you so firms can nanotarget ads at you. I hope most would
         | consider it to be unethical.
         | 
         | The concern that immediately comes to mind is that this
         | nanotargeting ability could be abused by (just to name a few)
         | spiteful ex-partners, stalkers, internet trolls, and generally
         | vengeful unpleasant people.

         | Assume you target an ad for an adultery service to your wife.
         | Assume she clicks the ad. Then the service (a mock-up you
         | built) will ask her for her name and other information. Assume
         | she gives the service this information. Now you know that your
         | wife is interested in adultery.
         | 
         | Interestingly, there is a different way to go about it.
         | 
         | Assume you create an ad for diamonds, and target it to people
         | who are into adultery. Your wife, who likes diamonds, sees the
         | ad, clicks it, and fills in her information on the diamonds
         | website (a mock-up you built). Now again, you know that your
         | wife is interested in adultery. But she is unaware that she
         | even revealed this information in her transaction with the
         | "diamond" website. She wrongfully assumed that all the private
         | information she shared with FB stayed on FB's servers only.
         | Note that this leak also exists in Google.

         | What if you're a stalker though? You can target a person by
         | his/her e-mail address or phone. Facebook used to allow you to
         | target as little as 20 persons. I don't know if this still
         | holds true. So you enter 19 fake e-mails and the one you're
         | interested in targeting. So eventually only a specific person
         | will see your ad.

         | 
         | Unless there is proof they DON'T do this, like some law that is
         | clearly enforced, or some piece of code that mathematically
         | prevents it from doing so... I think it is more than safe to
         | assume they can and they have violated privacy concerns.
