Is a 'whitelist' the converse of a 'blacklist'?
No. At least, not the common usage of the two terms.
The difference lies in things that are not listed.
Blacklist implies that unlisted things are trusted.
Whitelist implies that unlisted things are not trusted.
IMO most of the current white/black lists should be tri-state.
For example; tested open relay, tested not open relay, untested.
(Well defined metric scores with the additional "unscored" value
would be even better when possible.)
