It can't.

This idiotic idea resurfaces periodically (see "hashcash" and other
similar products of the wishful thinking of clueless newbies [1]).
It is one of the very stupidest anti-spam ideas -- and there's a lot
of competition for that "honor", unfortunately. [2]  I suggest that
you refer to the archives of the spam-l and irtf-asrg mailing lists
for a quite thorough debunking of this nonsense by the most senior and
experienced people working in the field.


[1] Hashcash fails on inspection because attackers control vastly more
computing resources than defenders, by several orders of magnitude.

[2] Including "anti-spam" ideas which actually make the problem worse.
See "C/R" and "SAV", for example.
