At the religious private high school I attended, all it took to make a student a “hacker” was popping open Internet Options on the computer lab’s XP boxes and disabling the proxy they were using. Had to sneakily do this sometimes not to view blocked stuff, but to just have a working internet connection to complete assignments with because the proxy service was provided by some terribly run local company that must’ve been three Staples special Celeron Compaq Presarios and a Linksys router in a shack somewhere, because they were constantly having outages.
