Why isn’t this DNS filtering default done by the ISP?

A lot of people view this as censorship. Once upon a time, people thought that spam filtering was dangerous because censoring email was evil, and so forth. Today, I don’t think there’s anybody who uses email that doesn’t use such filtering mechanisms. Likewise, I don’t think anybody should be using DNS without having filtering mechanisms.

This recognition should cause us to rethink what ‘nature’ and ‘wilderness’ really are. If by ‘nature’ we mean something divorced from or untouched by humans, there’s almost nowhere on Earth where such conditions exist, or have existed for thousands of years. The same can be said of Earth’s climate. If early agricultural land use began warming our climate thousands of years ago, as the early anthropogenic hypothesis suggests, it implies that no ‘natural’ climate has existed for millennia.
