I'm learning a language, I speak it in public to other people who do. I don't research the language, because I have some old text books on it. My partner doesn't speak it and doesn't research it on their devices. I don't normally have my phone on me in public, but my partner does. It took about 4 months of publicly speaking in the language before they got ads
What do you think this means?
::edit::
It was a Reddit ad and my city has embraced those AI smart cameras, so I assume some of those are Google owned which makes sense with Reddit and Google's recent alliance. This is assuming our devices aren't listening to us without our permission and AI cameras are mining data on passersby
Other theories are that since cellphones are involved it doesn't matter if I nor my partner ever searched for the language, at some point my phone or partner's phone was near someone who spoke that language and the data brokers/ad sellers inferred from there
Seems like the consensus is that I must have posted in the language on some social media or used Google to research it or made some new friends who speak the language and that's why
Oh but they totally are, it gotta make sure you didn't ask voice bots something. Anyway, its something you don't opt out of because that would require a totally de-googled device using lineageos or something and avoiding voice things, also it goes off IP rather than device. For example, my dad visited my house and started to complain about getting youtube ads in Tamil and then being amused by some of the ads and going down a youtube Kollywood wormhole. I do watch a lot of foreign film where my phone can hear me, so every once in a while I'll get an ad of the language of the last film watched, which is sort of funny ngl.
