Single mob camping rules?

[TheAngryRogue]

If, in an open zone, a player is sitting at the spawn point of a particular mob or its PH, and others show up to try and farm that same mob, what is the EXACT rule on contesting this mob?

The no KS rule makes it seem like the first to hit is the owner of said mob and anyone who hits after...is the KSer.

I grew up with Everquest. Anything that isn't part of a grouped "camp" has always been a DPS race. ESPECIALLY in open zones. Hill giants, named pathers, rare spawns...anything, has always been about who can do the most damage, the fastest. Yes this screws over new players just trying to get a quest item or an item they cant afford the price other players are asking, but its been the rule.

All I can find is that camps are to be argued over by the players and that the P99 staff does NOT define what a camp is, though the previous rule states that they can do this....so you can see my confusion. I'm new. I don't have a hundred thousand plat (or whatever ridiculous amount they have. Ive seen stuff selling for 200kpp!!) these farmers already have. I need these camps for gear/coin. Losing them to someones 23rd twinked monk and boxed necro is really pissing me off.
