A tag is why graff is even here today, and if a established writer has done and or is still doing his thing you shouldn't go over anything the person does, tags ,throwies whatever and when you do you accept the consequences of your actions. If the spots taken by someone that has more rep than you, find another spot. As much as people follow the unwritten rules, people always seem to skip the rule of respecting writers who really do their thing and have been around for more than a couple years.
