CHuck at letterheadfonts has been trying to implement software to stop this, but so far, it hasnt worked. He did however label the fonts you buy with the info of the sale in case you decide to give your buddies a copy and then like here, some idiot uploaded it to a file sharing site for everyone to get. I know the guy involved, even met him one time, and he seemed like a nice guy, but he had a chance to fix the whole problem early on and didnt, now its got to this point. I dont blame chuck for doing this. Piracy is rampant in the font and clipart field. Alot of people have no scruples and will try and get everything for free. Its really a shame. I know one thing, people who buy his fonts wont be so quick to give them to someone else anymore now that they know he has a way to chase them down.
