The Internet is filled with cultural riches, ranging from translations of ancient Mesopotamian texts to this inexplicable death metal video tribute to Arnold Ziffel, aka the pig from the 1965 sitcom Green Acres.

But that's not all -- the Internet is also home to a borderline unfathomable amount of pornography. And as a result, there are a slew of filters, software, and apps designed to make sure this roiling ocean of filth doesn't completely spill over into the workday, murder worker productivity, and tank the global economy. And given the all-consuming river of XXX fun this blocking technology must stanch, sometimes it backfires hilariously.
