ars posted this article today: https://arstechnica.com/gadgets/2024/08/its-not-worth-paying-to-be-removed-from-people-finder-sites-study-says/
takeaways:
- the paid automated options don't work very well
- easyoptouts had the best success rate at (only) 65%
- claims connections between the data sites and removal sites -- i certainly saw a few ads on the sites but nothing points any fingers at any of the services mentioned in the comments here.
i ended up using kanary and optery in the free tier and doing the removals manually. but to follow up on my OP, there's no service i've seen that goes any deeper than what comes up on google, which is disappointing. there are larger, private databases (such as lexisnexis) which was hoping to be able to get out of.
