@foone friends of mine were at some sort of a conference in 1999-2000 or thereabouts and the confident sales dude said “if you can find a url that has porn that we don’t block we will give you a 50 dollar gift card
One of them sat down and tried a couple, then thought for a moment and typed something, and porn popped right up
Turned to the other guys and said “yeah it doesn’t block Dave’s server”
