I have filed a few SPI reports with about 85 positive results and thus have seen what the CUs routinely write there I worked for a major ISP for a very long time and knew what the state of the art at the time was for identifying specific users as required under my contract at the time and I have also been a volunteer on a website where they routinely block people who try to fool the system into thinking they are two separate people Was there an actual reason for your post here by the way
