I'm quite familiar with password attack scenarios.
If high-value targets are selecting passwords that would be vulnerable to a targeted cracking attack, the solution isn't to blacklist a half-billion passwords (when they could just as easily come up with literally trillions of other passwords that would also be bad, yet are not included in the blacklist). The solution is to show them how to manage their specialized threat model - 2FA, creating strong passphrases, using a password manager, etc.
