Hi. About that points.
• Actions leading to an overload of the servers and/or can considerably adversely affect the game play for other users.
This rule refers to some deliberate actions that can result in breaking the game to other users up to unplayable level (server crash etc). If we apply that to spiking, then on that matter why not apply that to killing someone's WWK at home. This action would definitely "adversely affect the game play" for the WWK owner and their team.
Back to the spiking issue and more serious note - devs are currently discussing it, as I mentioned in another thread dedicated to that shortly before. I will come back to you in the nearest future with more information about it. Some time within next 10 days or so (can't say more presicely due to upcoming bank holidays).
