Whoa now easy, sperg mode is full on in this thread. If Nords didn't know the Grey Order/Union was multiaccounting, then they are not guilty. No one but them can know that for sure really. Like Thovex said, they did not want to not want to play with them based on assumption that they might still be multiaccounting.
What is certain though is that Grey Order/Union had some members multi accounting. Catch is, can we blame the Grey Order/Union as a clan for that? I believe so. Because there is just no fucking way, not even a single percent that the leaders and active start players of the Grey Order/Union did not figure out that some of their members are multiaccounting. Were those members encouraged by their leaders to do that? Probably, but we can't know that. One things sure, they did not do a single thing about it, so for that both the people multi accounting and Grey Order/Union as a whole is guilty as fuck. Will they kick/ban them from their clans now for the purpose of trying to restore their damaged reputation? Most probably not, because they don't give a fuck if they play fair or not, they want to win strategus and then brag on the internet on how they can manage their trades better or some similarly stupid shit like that.
Also Cooties, you cannot really compare our "cheating" to massive multiaccounting. As far as I know (I might not be informed enough), our worst crime was attacking our own fief to lock it down from being attacked, which was a completely retarded move by some of our members (or one), and I still condemn that action today. That's hardly comparable to multiaccounting actions in every strat. But the point is, even if we'd have some of our members multiaccounting and found out, we'd ban them. If we kept it silent and trying to hide it like GO/Union does and if I found out, then I'd crap on Fallen leaders head and say my goodbye, you have my word here and now.
