This may be very true - I don't have any direct experience.
Transitive trusts have two big advantages, which I was hoping to
utilise. Because trust between parties is somewhat inferred rather
than purely stated explicitly, the volume of trust statements can be
reduced. And connections can be suggested between two people who
don't already have a trust relationship in place.
Of course for different types of information, different trust
assurances will need to apply.

DanBri has a page on FOAF whitelisting at
http://www.w3.org/2001/12/rubyrdf/util/foafwhite/intro.html, but I
think that the intent was only to cover simple aggregation of email
hashes, not to look at the number of degrees of separation.
