I don't necessarily have to know someone "personally", in order to trust him,
or her. I just have to know him, or her, well enough - as I would, if I had
the opportunity to relate with such a person. (1)
And, alternatively, one can reveal (very much) about one's true nature, just
by the nature of one's work. (2)
Meaning that...
(1) People like Richard Stallman, for example, reveal a lot about themselves,
in the public talks they give - which are a very good way to know what kind
of persons they are.
And, (2) one very good way to judge a person, is by the nature of the work
they do. (Like in the saying, "judge a tree by its fruits".)
