Leslie Nielsen is such a bad-ass tagger that he doesn't even need to use his intials, or a short nick name. He uses a big black paint marker to claim his turf with all thirteen letters of his name. If the police happen to roll up on him in the act, he just flashes his badge, and says "Don't worry, I'm officer Frank Drebin working under cover here."
I found this tag outside of 111 mina last month after the nerdsalon.
