But aren't big cheap wins almost impossible?

I guess there is no technical solution to comment spam; it'll have to
be economic. A micropayment system might work, where you have to pay
two cents to comment (and thus "just my two cents" will have some
meaning again!) but the two cents is refunded when your post is judged
to be legit by a human. That has a far greater chance of being
acceptable for blog commenting than in email, where you don't want to
slow things down as much. This would also have the advantage of
killing off those idiotic "first" comments.

The one advantage this system has over normal moderation is that
spambots will be disinclined to pay to post, so the moderation queue
will be smaller.
