Some graffiti artists feel the need to change their names once they get a little heat on them. When you're just starting out it's common to change names because you haven't yet found a perfect fit. However once you find the name you want you almost can't change it, especially if you spent a few years on it because your name becomes who you are. Changing your name and ditching the old name isn't a solution to beef, or for getting caught. Think of it, the whole point of graffiti is to get a name and get it out there as much as possible. If you change your name every time you get caught you'll never get one name up enough. Look at any legendary graffiti artist. A lot of these guys / girls have gotten arrested on their way up yet they keep the same name because they are establishing the name. They would never have become a legend if they didn't establish the name.
