Right, that's what I'm asking. Is it known that Facebook pixel will log IP and Facebook will allow targeting like that? I'm not asking if anyone knows this is a product on offer or known to be done? Not asking for the wildest theory. Is there an IP path?https://twitter.com/Bobhunt5/status/1263624098120433667 …

Iphone (iOs), Safari, private mode. So the only thing I can imagine is the IP. Two separate machines/browsers and both browsers are not logged into anything and are in incognito/private mode.https://twitter.com/robinberjon/status/1263624507534856193 …

Right. Cross-device tracking. Though this was immediate. Look up - > ad. So I'm wondering if this is a product they sell? They just do it to increase ad relevance (free to advertiser?)https://twitter.com/SteveBellovin/status/1263625004442320902?s=20 …

No, not even once. Plus, I actually switch to brand new phones fairly often (don't ask; it's research). This phone was deliberately kept completely free of Facebook except for having WhatsApp on it. I have a single, separate device for Facebook.https://twitter.com/ilgnome/status/1263627147186405385 …

That's my guess: that there is some fingerprinting going on and all my devices are linked to my Facebook account. (They use same IP regularly). Basically, no amount of privacy options or switches on the platform or separating devices protects against this. https://twitter.com/aarongraves/status/1263625691750436870 …

I would love to get to know if anyone has clarity/information on this? It seems like a really important thing for people to know: forget not being on Facebook, even not being on the same device is protective of tracking via cross-device tracking/IP.https://twitter.com/WolfieChristl/status/1263629657230004225 …

Wolfie Christl @WolfieChristlReplying to @WolfieChristl @zeynepI don't have evidence, but I'm pretty sure FB pixel ingests the IP. In order to create household ID links and/or to feed it into their retargeting optimization algorithms (without advertisers having control over this). https://twitter.com/zeynep/status/1263625251260416002 …8 replies 17 retweets 73 likesShow this thread -

I looked up one brand, got ad for another brand.
It was a very very specific conversation, and I'm actually not in the market for coffee machines. And it was instant. Looked up, put phone down, turned on other machine, saw ad for other brandhttps://twitter.com/robinberjon/status/1263632775682437126 …zeynep tufekci added,
Robin Berjon @robinberjonReplying to @robinberjon @swodinsky @zeynepI'm curious, did you look it up on a brand site and get an ad for another brand? Or on an ecommerce site and got an ad to buy elsewhere? Because if so that's a neat smoking gun for the harms of tracking to publishers, brands, and businesses!5 replies 6 retweets 37 likesShow this thread -

All my searches are in incognito mode. I know it's hard to believe, but I actually research stuff like this for a living. I put everything in incognito mode and separated devices and sandboxed Facebook just so I could rule that out. https://twitter.com/adnanchcg/status/1263633265749090304 …

so about incognito—you’re still being tracked by a multitude of ways. it’s (i would dare to say) next to useless, especially considering it’s in the chrome browserhttps://www.hotspotshield.com/resources/can-ip-addresses-be-tracked-in-incognito-mode/ …

separate devices notwithstanding, all it might take is one login using one of your accounts on another device, or using the same devices close together. just once!!!

I am hundred percent certain I have never logged in to FB on the phone. I’m a researcher and I have sandboxed Facebook.

doesn’t need to be a facebook login, it can be for any service (including your email inbox, any e-commerce shops, etc). the unique identity (you) that Facebook is targeting is cobbled together not only by them, but a slew of 3rd parties, iehttps://www.facebook.com/business/marketplace …

didn’t mean to throw doubt on your browsing habits!!!!! i’m 1000% sure youre fully aware of a lot of this. but the depth of facebook’s partnerships is fairly murky and little discussed outside of trade publications
