Right. In practice we get out introductions
from a variety of sources, and we apply
discretion and due diligence to them as they
come in. No biggie. The main thing here is
to identify the source of the introduction, it
is not the agent’s job to do/measure trust,
it is the user’s job to make a trust judgement.
In that sense, the use of the word trust outside
of "Alice decides whether she and she alone
trusts X" should be treated with suspicion. I’m
glad this is starting to be understood:
