Judging by the adverts they show me, Facebook thinks I'm originally from a small city in Florida, that I moved from the US to the UK and want to give up my US citizenship for tax purposes, that now live in specifically both Cambridge and Waterlooville even though those are opposite sides of London, that I own a potentially dangerous breed of dog that the UK just banned, and that I'm a hermaphrodite in need of both a custom-fitted bra and dick pills.

None of those are accurate.

The only adverts they've shown which are relevant to my interests are for Babbel, except I already had that years before they started showing me the ads.

That's the craziest part. All the exabytes of information gathered, and the ads are still entirely irrelevant 95% of the time. Except when you've just purchased a product, then they think it's a great idea to show you ads of the very product you already bought!

So, you are telling me that you live two seperate and secret lives to hide the fact you own illegal dogs?

In all seriousness so, for all the effort and data companies like facebook have, the product, targeted ads, is just bad. And sometimes hilariously so.

Even if I owned a dog, which I don't, UK law is irrelevant because I live in Berlin.

So, you are an international spy? :-)

Seriously so, how is something like targeted ads a product worth paying for if the results are, quite often, so incredibly wrong? I get search context ads and such things, but all that targeted stuff is just so pointless. I never got a single one that was relevant for me. Since I aggressively turned off anything ad related on my phone, ad quality actually got better. Still not really relevant for me, but better.
