You might have heard the saying, common in policy and mechanism design: "Show me the incentives, and I'll show you the outcome."
If you want to reduce spam, you increase the marginal cost of posting spam until it stops. In general if you introduce a small cost to any activity or service, the mere existence of the cost is often a sufficient disincentive to misuse.
But, you can think through implications for yourself, no? You don't need me to explain how to think about cause and effect? You can, say, think about examples in real life, or in your own town or building, where a service is free to use compared to one that has a small fee attached, and look at who uses what and how.
