I am ashamed to admit that I did several applications for advertising on my car, back in the day before social media, when that was the most cutting edge way to shill for advertisers. It was right around the time that data harvesters started realizing that putting up applications for advertising on cars was a great way to get lots of free demographic data.
I haven’t heard much about this angle with the social media influencer market yet… there must be thousands of people who give away all their demographic info applying to get sponsored for every one who actually gets sponsored.
