Look if people are looking to find ways to work around the code and the game ethos, then I won't waste any time kicking them out. If you're smart enough to work out an exploit then you should be sharp enough to win without having to use it.
If winning is so important to you (generalised - not specific to anyone) then do it without tainting your self as a 'cheat'. Their is a League that has just been set up 'No holds barred' which can accomodate you, or you can go to MFN-1 the beta test league. if all you're interested in is pushing the envelope to the point where the game goes beyond the realms of believability, you'll be welcomed there with open arms.
My stance on the Punt block is you should be able to get the occasional block from the edge rushers. But not through the middle. Or very, very, very rarely through the middle. I think the rule I have in place allows people to develop a strategy for trying to punt block. It also allows people to have a strategy to prevent it happening (elite long snapper, elite level punt timing for the punter, your quickest pass blocking O linemen on the edges etc)
Players can play out of position, but come on, at least try to play the game with some integrity.
