Anti-linked with an individual?
Check whether this individual is anti-linked to any of the Personas in 
            Folks.Individual i. If so, true will be returned — 
              false will be returned otherwise.
Note that this will check for anti-links in either direction, since anti-links are not necessarily symmetric.
