@simon Do you have theory where do these "false positives" came from?
For example my recent meeting with this phenomenon: I visited my boss in his office and he had new server laying around so we talked about new servers for a while... And tada - that day afternoon I saw an ad for servers.
Is this simply Baader-Mainhof phenomena (frequency illusion) or does they have some side channels? (For example - both me and my boss were on same internet connection that day...)
@severak I think it's coincidence.
Anyone who speaks out loud likely carries a phone with them. Every day that phone is present for hours of spoken conversation.
A few times a year, people go "wow, that targeted ad is suspiciously similar to something I said out loud just now".
They're not taking into account the thousands of hours of audio which did NOT coincide with a relevant ad.
