Regardless how good a system is, someone will always find a way to cheat it. Sometimes, they can get away with it, but as was demonstrated in this case, the subjects got caught. After the fact, yes, but still, they got caught. And they got dealt with appropriately. All this reflects negatively on in terms of trust are the 2 members in question, not the system. This just proves that it works and the admins are being vigilant to make sure it isn't abused.
