So are you not a player, or are they not a player? PVP does stand for player vs. player, just because it is unilateral doesn't make it not player vs. player.
To be honest, it's not my favourite thing, it can be really frustrating. Yet at the same time, some of my favourite memories come from being ganked- I find some way to get out of their reach and then spam /wave at them, or something like that, or instead of trying to run or fight just press x and sit down. Sometimes they'll surprise you! You can get stuff out of being ganked too, you just have to figure out a way to do so.
These threads are kind of silly though, they pop up every couple days, and people complain, and all it really sounds like is "wah, I don't like how you play the game, so you shouldn't be able to do it." It's as much a style of play as any PVE, or arenas/bgs/duels. You might not like it, but other people don't like raiding, or battlegrounds, so should those be bannable too? How would you feel if people started threads asking for PVE to be bannable, just because they don't like it?
It's part of the game. It's PVP. Just cause you don't like it, doesn't make it literally the worst thing. Find ways to play with and around it, and you'll quickly find that it adds a degree of spice to the otherwise banal experience of leveling. These threads just feed the griefers. Stahp it.
