As you can see, "Eve" is in two lists, in one of them with a prefix "~".
~snip~
You might have noticed that Eve doesn't show up in the final list.
The reason is simply that Eve is added "positively" to the Trust List of Alice, but at the same time, by the prefix "~", Bob tells us that he explicitly distrusts the judgment of Eve.
The software will now calculate "+ Eve" and "- Eve", which equals "Zero Eve", so Eve won't show up.
This is incorrect: Eve would show up.
