Having done data broker opt-outs manually using the Big Ass Data Broker Opt Out List (https://github.com/yaelwrites/Big-Ass-Data-Broker-Opt-Out-Li...), very little of the process can be automated. Intentionally.

A few of these services ask you to go find your record among their lists first, so you can confirm which record you want removed using the URL of the record. So either it has to guess on that, or simply isn't doing it.
