Death Warrant

So I had my first run-in with Nubbie (Monk20/Rogue19/SD1; login name- Tyrswrath) a couple nights ago. I come to find out afterwards that Simon has had altercations with this douche-bag before. Anyway, here's what happened:
I'm running around the Subterraneum with one of my level 30's trying to grind out a level before I hang it up for the night. After running the circuit a few times, I was getting low on cleric buffs, but since I was close to level I thought I'd push it a little. I round the corner only to find a ton of spawns- my first clue that a level 40+ was in the vicinity. Usually, this isn't an uncommon occurrence in the Subterraneum because any Uber PC that wants a shot at Ryuji has to cut through there. Since azers and umber hulks are a joke for that build I pounce on them because it's good xp. Then I see Nubbie in the corner of the screen using HiPS. After a minute, while I'm killing azers one after another, Nubbie starts shadowdancing up and looting all of the azer bodies for hammers. I don't really need the hammers, but the audacity of this punk-ass to come in and steal from a level 30 was getting on my nerves. Still, it was more pathetic than anything--- a legendary character having to steal 8k hammers for money??? There are MUCH easier ways to earn cash in the Badlands with a decent build. Anyway, I'm still taking all of this in stride when Nubbie starts to get really bold. At first, he had been keeping his distance, but after a while he starts coming up and trying to pick pocket my PC while I'm fighting azers. That was the last straw for me. It's one thing to steal the hammers that I wasn't bothering with, it's another thing to try and PP my inventory. I consider PP a hostile action equivalent to an attack. I turn and try to get a KD in, which was evaded, but land a few hits before he disengages. Meanwhile, I finish off the few azers that were left. When the MOBs were gone, he asks me "you attacked me?", I said I tried to KD him because he got too close and PP'd me. He plays dumb (if there's one thing I can't stand, it's anuses like Tyrswrath that play dumb... recall that 'Ball' was notorious for playing dumb). Inconveniently, my happy green squares all start to blink as my buffs wore off. I try to slap on a couple fresh ones, when he jumps me and KDs me. I made a run for the sanctuary but didn't make it. A sneak attack got me before I made a safe zone. The last thing I said was "now you're dead". I logged in Gnimble since he's my legendary PC of choice for dealing with rogues and dexers. After Nubbie sells all of his unearned hammers in Dozo, he chickens out and logs in a lowbie (some sort of paladin/sorcerer named Freak). At this point, I'm exhausted and don't have the energy to hunt down his flaming homo paladin, so I log off and make a mental note to PK Tyrswrath on sight from now on. My guess is he'll just death log when I catch him anyway. Oh well, some people are just bitches.
