You're living in a fantasy world. Nearly everyone universally hates spam, and nearly everyone uses a mail system that automatically filters it. They don't sign a pledge, they just use tools that help then avoid spam. They mark spam they get in their inbox to help others avoid it automatically. And they have no compunction about using a site that relies on spam, they merely find it annoying.

And as I mentioned there's no formal system in place where users agree to see ads in exchange for access to content. Nor is there a moral obligation to do so.
