It uses Proof of Work to make some messages slightly more expensive to produce by performing a computation on your message that takes time to do.

For normal users that turn this on, it takes (in this example) about 1 second to publish a message, rather than instantly, as the computation is done. This is barely noticeable.

For spammers, who want to send out loads of messages quickly, it's just too slow to do.

Now normal users can activate a filter that will only display messages that have done this computation, leaving spammers invisible.
