Personally, I think all whitelists should be disabled by default (I
disabled all whitelists as of some years ago, and occasionally check to
see no new ones has cropped up).
That way is someone wants to allow others to decide who they can trust

given based on third party advice, and most definitely never ever
bought), so they must explicitly allow it.
