Is there one to show you what the ad industry has on you, and perhaps how it can by it?
If people had insight to this for how much longer would this be a problem?
I imagine there’s a website that does this which was launched five years ago.
Privacy International did a piece on this kind of ad-tech data survaillance and they were saying "Here is the shocking details what an ad-company knew about me when I asked them to share everything with me in line with GDPR"
Then I emailed Privacy International, asking: How did they even knew your real name?
To which they replied "Oh, yes, we forgot to add that to the article, I actually gave them my name and my cookies, so they could tie all their cookie IDs to my name"
PI promised to add this "small detail" to the article. They never did: https://privacyinternational.org/long-read/2433/i-asked-onli...
They also promised to write an article about the implications of pseudonymous data and the possible link to real identities, which they also never did.
Some of the big challenges of the system was a) convincing requesters that we couldn’t look them up by name and b) teaching them how to find the things we could look them up by (cookie Id or apple/android advertiser Id).
It was one of the ugly ironies of the system that we had to build a name collection capability when we didn’t want it.
I mean, even without originating an actual ID, how many bits do you think it takes to uniquely identify you in your geo? It wouldn't take much in the way of resources to track everyone in the US who uses the internet; a few trackers on popular websites, localization services: I'd be shocked if there weren't things like this in existence already for bail bondsmen/private investigator types.
Many many companies in this industry attach real names and email addresses to this data, and even the ones that aim for pseudonymity do it typically in a very weak way (such as an unsalted md5 hash).
