Found trust
Found trust is trust (measured as social capital) that existed between people before they encountered some system.
Once they are in that system, built trust and grown trust expands.
However, if there is any question of the premises of that trust being false or challenged, like an audit reveals that some people are masquerading as others, the found trust can be affected too. For this reason why a faction or political party starts to use some system (e.g. wiki code) they are very concerned with how reputation is reflected within it.
