A few years ago someone did a data export from linkedin and received a CD, I think either in the early days of GDPR or maybe during the predecessor (NL: WBP) which was effectively the same except no fines. One of the takeaways there was that linkedin suggests users to each other that share an IP address. I have also noticed that youtube on tv will suggest things that someone in the household watched on the phone. Whether it's truly by IP address or by some other proximity proxy, in the end the answer is the same: yes, adtech firms use correlations, such as your IP address. It sounds like you're one of today's lucky ten thousand. https://xkcd.com/1053/ https://xkcd.com/1053/
