My policy on various blood bowl code of conduct issues:

Fouling
The only reason why I don't foul every turn is because I don't consider the benefits worth the risks or my players have more important things to do than waste their action on fouling. I will never make any agreements regarding not fouling, even if you have a dirty player and I don't.

Crowd pushing
I just love to crowd push, so beware! I won't do it unless I gain something from it, though.

Making pointless blocks to get SPPs
Yes, I do this. Sometimes even when I don't want the SPPs. It's a spinal reflex.

Stalling
It's a perfectly valid tactic. I love it when my opponent stalls, because that means I still have the chance to prevent the score. And if I fail, at least I'm not going to lose 8-0 or something like that, due to the turns spend on stalling.

One turn scoring
It's a perfectly valid tactic. I attempt this whenever I have exactly one turn to score or when I'm down to very few players and a OTS is the most probably way to score a TD.

Chatting while playing
If you say something, I will respond but otherwise I'm not particularly chatty.

Having a very good win ratio
If you think this means you are a good coach, I'm sorry to burst your bubble. Unless you also have a very high CR, all it shows is that you prefer to play easy matches.

Complaining about your opponents poor sportsmanship or coaching skill
Either you're right, and then you shouldn't have to play against me again, or you were just trash talking in a very rude manner.
