From time to time, i see posts here talking about tagging, and using it to spread some "important message." This is one of the stupidest things i have ever heard. Tagging is vandalism, and when you are caught, you will be fined and sent to jail over stupid bullshit. This is probably why the ops do not seem to stick around long, because they get thrown in jail for vandalism, and their important message gets crushed because they were too busy being retarded. Furthermore, it is time consuming, expensive, and you give the police probable cause to search you if you have spray paint and good magic markers on you. The easy, cost effective alternative: Home made labels and stickers. Labels peel right off, which means YOU WILL NOT BE BREAKING ANY VANDALISM LAWS, SO YOU CAN LEGALLY SPREAD THE WORD ALL DAY LONG, IN PUBLIC. However, i recommend being sneaky about it anyways. You can put the labels in places that could not be tagged before, and because they peel right off, janitors for some stupid reason, do not remove them as quickly as tags. (I have verified this with "experiments") This means that you can put a label right where people will see them, like above urinals, in stalls, at eye level to doors of fast food restaurants, on pens, anywhere.
