Precisely to establish that the registrant humanly responds to
messages at its published addresses.   The registrar would have
to employ a CAPTCHA on his token-accepting site; otherwise
clever rogues would automate the token-submission process:)
But this is all trivial and done daily by numerous institutions.

Sascha perhaps your question arose because I was imprecise
in my brief earlier message; this procedure would not be an 
anti-spam measure, but it would greatly simplify the next steps
in anti-spam processes if the registrar community ever becomes
serious about halting spam (itself again easy to do but
that is the subject of another message).

Kind regards to all
