At one of the large companies I've worked before, the corporate filter barred access to https://graphics.stanford.edu/~seander/bithacks.html https://graphics.stanford.edu/~seander/bithacks.html because it was a hacking website. Which it cleverly determined, you've guessed it, by checking the URL and seeing it had "hack" in there. Everything with "hack" in the URL was banned. Pretty sure all those JavaScript ninja hackers they'd hired were a little baffled that they hire hackers but don't let them view nasty hacker pages...
