I agree that terms like &quot;dark web&quot; and &quot;deep web&quot; have been used so much (and often interchangeably), that they&#x27;ve mostly lost their meaning. That being said, I&#x27;ve always used &quot;dark web&quot; in reference to things like hidden services, i2p, etc, and I&#x27;ve used &quot;deep web&quot; to mean unindexed&#x2F;inaccessible content.
