"You may dream about this, but no one ever does it. Until now. Frank Jonen, who runs his own small Web design company, claims he wasn't paid properly by Fitness SF, one of his clients. So, he went and replaced the Fitness SF website with an angry letter about how evil the bastards at Fitness SF are....." http://www.adweek.com/adfreak/agency-replaces-clients-website-nasty-letter-after-not-getting-paid-147291 http://www.huffingtonpost.com/2013/02/15/fitness-sf_n_2698555.html I find this pretty relevant to me, since I actually go to the Fitness SF Gym. I don't know about the guy, but I just realized how stupid the management of this gym actually are. $5,000 upfront for http://fitnesssf.com??? I could sit down on the toilet and shit out a better website than this guy. As for defacing their website....well, what else is there to do if you live in Germany and you supposedly get screwed out of getting paid?
