Actually, if an account was linked to an assigned code number, not an actual name, it should be very easy to accomplish. Prior names should still be "copyrighted", so copycats could not then utilise them to cause trouble. An added fee for new names might both discourage people from doing so, or allow only certain stats being shown. No use changing from 888 to 666 when your old crowns still show who you are. (Appologies to 888, yours was the easiest name to use, especially with the 666 change example, no offense intended). A simple 8 x gold crowns, 4 x Silver etc as past achievements would suffice, and hide (From most) who you were. There are so many people changing names, instead of it being a problem for the game, the Devs should make it a money earner for them, utilise what is already happening.
