Yes friend, you made a point about RC. Have not thought about that possibility, but it could be a nice solution to spamming. But how about a determined spammer who has all the resources needed to create multiple accounts. Just like those with big SP accounts downvoting innocent authors at random?

There is what is known as cost-benefit analysis. Spammers are rational beings - when the marginal cost outweighs the marginal benefit to be derived, chances are that spammers will stay away. Why spam when it comes with a cost? We'll see.

Okay. That would be frankly a problem that would give us headaches.
