Have you read Matt's note: "Bitcoin has a brilliant spam mechanism: transaction fees."

That means, fees are a filter for undesirable transactions (spam), which could be payment for goods or services that someone can't send because the fee is too high. 

Is it OK to say to that person you can't pay the fee, it's spam? I don't agree with that statement. This has nothing to do with Bitcoin.

If you agree with Matt, that's fine, no need to get contentious.
