If the purpose of their letter writing campaign is extortion, isn't it mail fraud to send these letters via United States Postal Service? I have a client that received a few letters almost a year ago. I replied to the letters requesting registration information, which I knew they did not have because they had not registered the images. Now, almost a year later, McCormack has written with almost the identical letter initially sent to my client. Knowing they did not register the image and knowing that the image was taken down from all my client's servers after having been up for a mere 3 days, isn't it mail fraud to send continued correspondence intending to get money?
