eli5: how does selling data work? why exactly should i care about wether or not something is selling my data to others?
In: 22
You updated your Facebook profile to include your age of 25. Facebook takes that info and goes to advertisers and says “hey if you want to advertise to people in their 20’s i can do that for you”. The advertiser says “yes please, advertise to these 20-29year old”. You’ll then see the ad.
