Tales from the corporate firewall: Yesterday I couldn't access a website where "rechtsextremismus" (Right-wing extremism) was part of the URL. Obviously that URL contains sex and should therefore be blocked. -_-
Ha. Similarly a friend once told me that in days of yore she worked at a place where “postits” (as in, will you please order some more postits) was automatically transformed to “post*ts” in their intra-office chat system.
