Since that'll never happen without toppling the money printing machines of several of the world's most powerful companies, I'd like to repeat an idea that I once heard -
A publicly available clearinghouse of all targeted ads published via a service so that researchers can find out
- Every ad published
- What targeting parameters were used, other basic data about the ad
- How many impressions the ad received
- How many clickthroughs, etc
It would not include any PII of those who saw the ads, only on the ads themselves. Bonus points if we can also have some kind of GUID "advertiser_id" that would allow researchers to tie the ads back to some kind of probably-anonymized-but-maybe-not entity that published the ad. The API would be defined in the regulation so that vendors can't pull any obfuscatory fuckery.
Sunlight is the first step in stopping this.
