I'm okay with fouling in many situations. Got the ref? Then use it. Got a key person on the ground? Boot them. These are things I accept.

I do not like fouling late in the game when you are obviously ahead. If I have three skinks on the pitch and that's it, versus your three trolls and eight snotlings, and it is late int eh game, then I think it is poor form to foul. You gain no spp, and you are not in a better position because of it.

I take only actions when there is an in game advantage to them. Will I foul you when necessary? Sure, and I'm fine with the same back. If I am playing one of my bashy teams and you keep your players on the ground to avoid them getting squished, that's also bad form, and I will become a foul-a-matic.

However, I think you need to only take actions that benefit you. Fouling late, when you are way ahead and the opposing player is no threat is bad sportsmanship. I'll put you on my blacklist, and that is the only reason I will do so.
