No obviously not. It's forbidden by the rules and creates an unfair advantage for your regiment. I remember losing points over this issue aswell. (correct me if im wrong it was some time ago)
I did remove the Nr.4 a couple of points in previous CNWL seasons, mostly for individual cases of double-regging and bad behaviour.
I do agree however that this is no argument to bring here and now about this particular case. Using past affairs to judge a regiment isn't the right thing to do, especially not if this judgement changes the actual thing we're discussing in the first place.
The decision I'd stick to, but that's just my two cents, would be a player ban plus a round removal of 1 to 2 rounds. This would be a way to punish the cheating team (as Tardet rightfully explained, one cheating player can impact the whole team whether it wants it or not, I am
not calling the 1er cheaters at all), without ruining a truly dominating result like 8-2 or over. In this particular situation the score is 6-4, so I assume it was a close game, in which cheating might have done an actual difference. A round removal as a punishment would change the score to a fairer result, like 5-5 or 4-6.
In any case it's a tough decision to make and we as a community should try and actually work towards finding a viable solution, because this might happen again and we need to be clear on what to do if or when it does.
