Is there anyway to stop people from killing you

[Baajikiil]

Is the only way to avoid these people to just exit and then find another game? Or is there a trick that I can do to avoid them (besides making private games)?

Basically the only sure way is to play alone, but that's not really what we're after if playing on the realms...

PKers can always ruin your game, but once you have alot of experience on the realms, you should be able to spot them a mile away. I tend to play alone first, and get a feel for the players in the game before I party with any of them. Also, when someone suspicious joins the party, I leave the party to avoid becoming a target.

I find it quite fun to play on open pubbie b.net(in HC), but risk of PKers is not 100% avoidable.

Also, taunting PKs seem to make them go away if you have good taunts.
I often tell the other players in the game, "Gee, this guy must have read the PK handbook; PKs always say the same things."(or somesuch) There is not much rebuttal to such a taunt, because it's true.

Also, if ignored for a few minutes they almost always go away as well. Go get a drink or have a snack. When you get back, most of the time they'll be gone.
