After unsuccessfully trying to bill his client for a website design project he worked on, Frank Jonen, a freelance designer based in Dusseldorf, Germany, decided to take his grievance to his client's company website by replacing the homepage content with an angry letter explaining his situation and calling on other freelancers to "stand against crooks like this." As expected, Fitness SF came up with its own explanation via its Facebook page, but no word yet on if or when they're going to get their website back.
