Freecorder 6 places an advert at the bottom of the page. I reverted back to Freecorder 4.
That's not quite as bad but your average user isn't bright enough to know the difference and will blame the site for things it's not responsible for doing.
When I was running web hosting we almost got into a major legal battle because some wackadoodle customer was seeing something happening to his logo and swore the server was hacked or we were messing with it, sent us screen shots, and nobody could reproduce it, not even other computers in his own office. His browser cache was corrupt and after I insisted he reset it and reboot many times, he finally did and all his problems mysteriously went away yet I was still staring at letters cc:'d to lawyers and impending calls from lawyers. Never heard from him again on the matter (typical) and got him off my servers at the first opportunity when he needed something and we, um, couldn't support and recommended he try a competitor :)
