The Fediverse is made of humans, and humans are not publications, even when we publish. So here, there is still a strong social expectation and culture of opt-in (affirmative consent), not opt-out (assumed consent).
If you want to run a successful service here it has to be opt-in, not opt-out. We realise this may run counter to your expectations, and may make your business model impossible here, but it is nonetheless the case.
My “profile” is on many scraper websites, which have aggregated what they can find out about me without my consent. Nobody likes being listed on those sites, but also on the wider Web there is no practical way to stop it. Here, it is trivial and normal to share information about and block opt-out “services” like yours, such that to date no such service has succeeded. If you have investors, they should know that you are attempting something high-risk and unwanted.
Either find a way to do this opt-in, or expect to be shunned, blocked, excluded and otherwise obstructed by the people of the Fedi.
