Are we sure that reputation is the issue? If we could look somewhere and
determine whether Dave Crocker allows anyone to act as his agent then we
can determine whether the claim of agency is valid without having to
worry about Michael Hammers reputation.

And so too is the reputation of Michael Hammer. Why rely on reputation
when one can get a direct answer?

This Hammer fellow can do whatever he wants but that doesn't and
shouldn't involve Dave Crocker if Dave Crocker doesn't care to be
dragged into it. It has nothing to do with reputation. Your assertion is
almost like someone listening to the neighbor that says it's ok to go
pick Hammers apples despite Hammer having put up a no trespassing sign.
I haven't raised the formal delegation (positive) situation - I have
only raised the "I don't delegate agency to anyone" (negative)
situation. Not very complicated at all.
There may be value in including a formal delegation capability but that
is another discussion.
