LinkedIn's growth, much like Facebook's, can mostly be attributed to the use of its "contact importer," which seems to have been where the 18M email addresses came from. Generally speaking, you should read the fine print when using such "features".
I do see an issue with part of this complaint: storing hashed emails and uploading those to use for targeted advertisements. The general consensus seems to be that even under the draconian rues of the GDPR, a hash of an email is not personally identifiable and therefore that data would not be subject to the GDPR. It appears that the DPC overstepped their bounds on that specific aspect of the investigation.
- reaperducer 8y agoAn e-mail hash is more specific than an IP address, yet from what I read on HN, IP addresses are considered PII by GDPR.
- fizx 8y agoIP addresses are more promiscuous than email addresses--i.e. your family and neighbors are relatively likely to share an address and/or subnet. That means that your family can see ads targeted at your bad habits that they might not otherwise be aware of.
- ndnxhs 8y agoI regularly see YouTube recommendations for the stuff my bf is watching and we don't share a computer and he is not logged in to YouTube.
- jobigoud 8y agoFirst time I hear about this. This would be very serious. Are you positive there is no other way, the Youtube recommendation algorithm is notoriously weird.
- Rjevski 8y agoI can confirm. I have very specific interests on YouTube (old cars, etc) that wouldn’t normally appear in the clickbait bucket aka homepage. When I opened YouTube on my friend’s computer connected to my WiFi (absolutely no way she’d get my YouTube cookies, and if anything she should have her own cookies) the front page had some of the stuff that I watch instead of the usual clickbait. Now I don’t watch anything that could be compromising but I can see this being an issue if someone is watching “sensitive” subjects and anyone can find out by just requesting the homepage from their IP.
- ndnxhs 8y agoI'm not positive about anything from google because I can't see how it works. All I know is he is on the same network and we see recommendations about stuff the other has watched
- travem 8y agoAn email hash can be used to identify an individual and so would very much be in the scope of GDPR, the same as any other number used to identify an individual. Curious why you think that would not be the case. It seems to fall squarely into Article 4’s definition of personal data.
