That's interesting, because in most games the people who exploit bugs in a game are banned/removed/punished. It's standard practice in online games to punish those who use the game in an unintended but presented way (exploit bugs).

David Sirlin has a chapter in his book "Playing To Win" entitled, "What Should be Banned?" It's about tounaments, but it may apply here as well: http://www.sirlin.net/ptw-book/what-should-be-banned.html
