We don't have similar qualms about voluntary mass blocking of ads.

I think the reverse assumption - that everything should be considered a valid information source until conclusively proved otherwise - is probably a more dangerous bias than assuming that some media does add nothing to the world.

That logic suggests we should ban free speech and only allow certain people and organizations to be registered as valid information sources, preferably after passing some sort of test that shows they're legitimate and trustworthy.

I have an idea, why don't we just filter out all the obvious spam sites?
