Diabolik, I'll make this clear to everyone here. WHOEVER is moderating for us, while we are away on tour, has explicit instructions on how to moderate. If a thread goes off topic, and is NOT ND related, it's to be deleted. Period. We do this when we can't check the forums every day, to stop any spamming, or trolling. You guys never see the garbage posts, because we moderate everyday, and we're on top of deleting the garbage. It's one of the reasons we haven't had the same problems as other forums here.
SO, when I tell my wife something like "Delete all posts NON ND related, NO EXCEPTIONS until we get home" she does so without prejudice. If your thread started talking about the Agalloch show, then you hijacked this thread, and she removed it. When we're home, we decide what to allow, and something like this would most likely be kept, but to eliminate any possible issues, the moderator is told what to do. This was posted clearly in the sticky thread.
Next time, start a separate thread about something like that, and it shouldn't be an issue.
