I had been logged on my Facebook on the second computer. I literally have a Chromebook whose key purpose is for me to log on to Facebook in guest mode. (Part of my experiment in tracing these things). That computer has none of my accounts logged in. None. https://twitter.com/soupkitchen/status/1263623319946842113 …

I know some will think it's the microphone but that's implausible (only FB app on phone is Whatsapp and I think we'd know) and also really burdensome (they are going to transcribe conversations?) and also why, why, why? Illegal, big risk, not necessary.https://twitter.com/proteantimes/status/1263623698520477697?s=20 …

zeynep tufekci Retweeted Queer as in fuck me
I normally tell people exactly that, but I systematically look at every Facebook ad I get and make note of any new category. Absolutely the first high-end coffee maker ad I have seen on Facebook ever in my life in at least last decade of being on Facebook.https://twitter.com/sextoyspolitics/status/1263624187534405633 …

Queer as in fuck me @sextoyspoliticsReplying to @zeynepSo it's POSSIBLE that this is just the first time you've ever *noticed* a high-end coffee machine ad, because you had them on your mind, and our brains do work that way. But I would also not be at all surprised if this was a case of tech surveillance.6 replies 11 retweets 90 likesShow this thread -

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 …

zeynep tufekci Retweeted Wolfie Christl
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 18 retweets 75 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 7 retweets 39 likesShow this thread
This thread is going to turn out to be content marketing for a coffee maker, isn't it? "Somehow Facebook tracked me and showed me an ad for the irresistible, satisfying aroma of the ACME-3000"
