Yep. But, even though I didn’t suggest it, I didn’t explicitly say that it didn’t mean global blocklists. So I clarified it, and added a footnote with more detial.
As Instance-level federation decisions reflect norms, policies, interpretations, and (sometimes) strategy discusses, opinions differ on the definition of “bad actor.” So the best approach is probably going to present the admin of a new instance with a range of recommendations to choose between based on their preference. Software platforms should provide an initial vetted list (along with enough information for a new admin to do something sensible), and hosting companies and third-party recommenders should also be able provide alternatives.
