ESIC should NOT be the ones who should be handing out the bans in general, especially not determine the "lenght of those bans". They clearly have noone in charge with experience that have dealt with these kind of matters (shown by the lenght of bans from the 37's) - they make themselves look not as professional with this, even tho they did a good job catching the bug exploiters.
Any coaches who claim he isn't guilty should explain why he doesn't talk to an admin about the situation. If you did nothing wrong give the decision to the people in charge. Then any action that followed is made by an admin or the TO and then you shouldn't be banned.
But you have to do it immediately.
All Coaches didn't do it so all coaches deserve their ban.
