This is why we can't have an open libertarian Internet, and instead have walled gardens and moderated forums - ordinary users don't want to deal with the crap.
It's also why we don't have open API's, and why the API's that the big providers do give us tend to be nerfed and then discontinued - they're constantly abused, which imposes a maintenance cost that businesses have to justify.
It's why an email server is so difficult to run and email delivery is so unreliable. It's why you can't (or shouldn't) rely too much on Paypal. It's why governments effectively outsource Internet policing to big providers.
And so on.
