Hello thanks for the question, I'm pasting a note that I wrote in a previous I-D:
(I'm not entering here into solution discussions!) Regards, pars 4. Name collisions With the traditional phone book, the querier can filter the returned results using some other information about the target user e.g. the street address, company, etc. A similar solution may be adopted. Along with a Turing test, the target host may return some information helping the querier make the right choice. If the target user is unlikely to be the right person, the querier can give up the query and avoid solving an unnecessary Turing test.
