The rules for non-ISP businesses are different than for ISP businesses.

We do this (block large tracts of Asia, Europe and South America), and
the only time a problem has been reported was when one of our people
posted to a mailing list and someone from a blocked region attempted to
reply off-list and got bounced.

The regional blocks plus open relay lists maintained by calmer persons
go a long way towards reducing the spam that makes it in to us. Accurate
dynamic-IP DNSBLs from the larger ISPs would go a long way towards
squelching the remainder.

  There is no problem that cannot be solved by the appropriate
  application of high explosives.
