Any 3rd party service or individual doing opt outs should limit data sharing as much as possible. Steps to do that include setting up email aliases, searching data in separate queries, using a proxy or VPN, verifying data exists before sending a data deletion request with all your pii in it, pushing back on any invasive requirement for govt ID...

It's tempting to just automate sending a mass email to all the brokers with your full name, DOB, and address asking for deletion (some services actually do this - beware), but that exposes you to a bunch of new spam.

I've been building Kanary for 4+ years (we're a removal service & YC grant recipient) and we take a conservative approach to each site. I wrote a bit more about why this matters: https://www.kanary.com/blog/dont-get-spammed
