OK my 10c worth.
Lets forget the hows and whys Tomb removed his bounty, because thats something else.
Lets go over why PK and PK for bounties fails.
The previous post illustrates it in full, a clan member dies for the simple collection of a bounty posted by whoever (for sure was not one of Tomb's clan he's not in one) and then 2 other members of that clan hunt Tomb. Now I would say that action would have been understandable had there
A: Not been a bounty in place
B: Killed this person several times.
C: The person initialy killed did not
i Run off at the mouth on any channel
ii Initiate the combat and lose!
In short 1 simple PK turns into a clan war or single character beat down by multiple chars of the affected clans members.
And before anyone says it... WE ALL DO IT.
