Are there host lists for pihole/adguard/ublock for these kinds of domains?

I'd assume the domains change regularly if it's malware or bot networks, but because they rank so high in this list, it sounds like it should be feasible to keep a blocklist somewhat up to date.

I think this problem even has a name: HARKing - Hypothesis After Results Known.

One way to mitigate it is to pre-register studies as it's done in some areas like clinical studies.
