Spot on.

Elsewhere in the thread gsreenivas mentions that the solution is too expensive for spammers and so they haven't had a problem with that yet, so we've actually moved to the original solution to spam: charge for sending e-mail*. The original proposal was to charge per email but an annual subscription would have the same effect in the right market (for now.)

* Wasn't it Bill Gates who suggested that?

But isn't this charging also for receiving?
