Sure, but do you expect all consumers filing CCPA complaints to understand this? Even the more astute consumers filing complaints probably don't understand that Maxmind provides both flat files and API as a service for IP lookups. They should set expectations here.
Maxmind could be completely transparent here to consumers, for those who don't understand the consequences of requesting a removal using the current implementation:
Thank you for your CCPA request which we have fulfilled. Your IP address has been removed from our databases.
Furthermore, your IP address has been placed on https://www.maxmind.com/en/accounts/do-not-sell-requests for the next month. During this time period, your IP address will be displayed on this page. Of course, no other personal information you provided us will not be included. Please note that no specific privileges are required to access this page, other than an email address to create an account. We have no realistic countermeasures against this, or potentially hostile actors who may regularly archive this page content.
