There is no denying that and no type of mental gymnastics you can do to justify it. Obviously both sides are going to be VERY large and there are going to be some people who hack/cheat/exploit. You will inevitably be able to find examples of members doing it on both sides from at least some members. There is a HUGE difference though between random members doing it and a guild condoning/encouraging it from the top. There is a HUGE difference between random members doing it, and it being literally part of a guilds race strategy. Guild leaders can only control what their members do to a certain extent, but when hacking/exploiting becomes encouraged and part of your guilds strategy, at that point anything you accomplish is null and void.
Despite how many great players you have in the guilds you run, and how you could potentially be a good legit leader, you will never be given legitimacy because of the fact that cheating/hacking is always part of your guilds strategy and always encouraged from the top down.
