Every week I actually go through and remove a couple dozen advertisers who upload my contact data to Facebook so that they can't target me. It's annoying, and unlike some other features Facebook doesn't allow me to simply not allow this type of advertising.
Every week I do this.
FB lets me disallow OTHER types of advertising. But not this type.
Isn't that what the setting "adds based on data from partners" are for? (guessing what it will be named in English) I have set it to not allow and have never seen an add from any of the 8 companies who have uploaded my contact data
No. Here's what the info box says about that existing privacy feature:
"Products that are provided by the Facebook Companies, including WhatsApp and Oculus, as well as Facebook Products like Facebook, Instagram and Messenger."
That has nothing to do with non-Facebook companies. It's something else entirely.
Maybe different settings for different regions, probably connected to GDPR. Directly translated the 3 info boxes I get say: Ads based on data from partners, ads based on your activity on Facebook Companies products (seems to be the one you have), and Ads based on your social activities (for instance pages you like). The 2 first can be set to not allow and the last to none.
That first one is "Data from partners includes your use of partners' websites and apps and certain offline interactions with them, such as purchases."
This offline interaction data is different from contact data. The latter doesn't involve any "partnership." It's a completely different part of Facebook ads.
Why? You're not removing their knowledge of you, just their ability to target you. It doesn't sound like you're doing this for grins, what do you get out of it?
I play my own part in this massive economy that exists of selling data to be used in Facebook ads (Google and other big tech companies do it, too). To me, it's the number one most dangerous thing that has happened to the web. It's my belief that you can make a direct tie from this type of advertising to the layoffs of journalists. That's a more complicated argument than I have time and space for here, but that's why it's an important issue to me -- I think it's a problem for democracy.
Edit: I also tell people I do this to spread the word about the practice and FB's failure to provide proper privacy tools -- in person, but also in forums like I did here.
