That's the wrong test. The test should not be "does this mechanism place a 
burden on the innocent?". All new mechanisms do that.

Instead, you should ask whether the mechanism places a disproportionate 
burden on the innocent. The burden should be at least somewhat less than 
the burden currently imposed by spammers. That's a much easier test to pass 
if you include the burden on sys-admins. However, the burden placed on end 
users should not be a cognitive burden - most won't cope.
