Ask HN: How does the Reddit iOS app get its content for targeted ads?
Hello,
something extremely weird happened yesterday and I would like to understand it.
A colleague came at my desk and we discussed his new "Nike air force 1" shoes. There was a lot of trolling about them for 5-10 minutes (they are the ones with the purple things on the sides).
At that time, I didn't know anything about these shoes, had never seen them nor look for information about them in Google/Bing or any other Apple products.
One hour later, I saw an ad about these specific shoes on the Reddit iOS app. Since I never wrote anything about them, could it be that the Reddit iOS app used my iPhone's microphone (locked and in my pocket) to get such information?
Where does the Reddit iOS app get the ads shown to users?
Thanks.
