Alter the trust algorithm, s.t. it requires trust derived from someone
that you have explicitly set a value for at some point in the web before
you start to believe any trust values inheirited from someone that you do
not personally know.  Which is how communities work in r.l. anyway.  The
evil dude can build up his little circle of aliases, all he wants but I
will place no value in that rating until someone that I trust says that
someone in his web of lies speaks truth.  We may want to be able to apply
negative values (I know that 0 is a liar, but I think that the caption was
meant as a joke) so that we can have inheirited distrust.  If you someone
I know has been actively been screwed, I will want take that into account
long before I start looking at what random strangers say about him.
