When I was leveling up Auro on harbor quests I had the pleasure of listening to some guy scream about people killing him in pvp. He demanded that no one over a certain level touch him as he was there too fight only that level. It went on for quite a while. Next day, in harbor again, and guess who was back in pvp, yelling in general about getting killed by higher levels, demanding again that no one but those he agreed to fight him. Finally morbid curiosity got the best of me and I will admit he is the first person I ever used my ddo on...he was a lvl 7 cleric with next to no hp, don't think I've ever laughed so hard.
I usually end up hearing someone in the harbor getting mad about something in pvp when I'm there... ohya, in Khyber
