I've used this as a bit of a thought experiment, and also think it may do more harm than good--but a part of me wonders if it may be just thing to create change. A non-profit that works a bit like haveibeenpwned.com but with data sold by data brokers that anyone can look up, with corresponding source attribution. At one point, long ago I was of the idea that all data should be public/exposed or none of it (this ship already sailed with data brokers and such. Don't know how it could be undone).

The problem I keep running into is a real world take on the Trolley problem[0].

Do you publicly publish all data, which:

1. Reduces its sellable value

2. Makes people aware of how much they are being tracked and profiled

3. Gives back a small bit of agency over ones data by knowing where to send delete/remove request to make data brokers honour local laws

However, doing so would also:

1. Give easy access to abuse victim data, putting them in further harm

2. Give actual stalkers an easier path to their targets

3. Other harm that I can not fathom at this point in time

I don't know the answer, maybe mask the address part, or do like Strava and set a blocking geo fence around home/work addresses. For location tracking keep it months behind and remove/mask anything remotely related to health services (mental and physical).
