Isn’t that the point, to fuck up digital advertising accounts so the data is unreliable and can’t be used?

this will cause problems for independent website operators.

This may seem to be a legit criticism at first, but AdNauseam allows ethical ads so anyone using good, safe stuff should not get affected. There is an entire section in AN’s documentation about not clicking on this specific ad group.

As for the vast majority of the rest who don’t use ethical, non-tracking ads: let 'em have it! ⚔ AdNauseam users (and users of any similar tools; I don’t know what else is out there) must first hold a fundamental view that the tracking world is extremely violating, of which ads are a subset. Long gone are the glory days when ads were funny, appealing, and well-made, and didn’t track people; ad companies gather data on us and if they get hacked, that info flies out in the open: all without our knowledge or true consent. Is that something you’re fine with? Additionally, more and more ads are proving to be entire scams, or otherwise shams that did not fully deliver, that have harmed consumers who legitimately click through.

The long-term goal is to teach those who use malicious ads that this is an unacceptable, unsustainable practice and that they need to market in better ways if they wanna keep doing this (again, going back to the pre-Internet glory days when Coca-Cola, etc. ran awesome TV ads and when there was no or nearly no account-tracking—or just any semblance of it).
