Take your point, and I'm sure it's possible, but I'd be agin it. If the stakeholders in the Black Pearl Limited Public Issue wish for discussion on it to be discontinued, then that's not a problem. But they were the ones who started this thread.
Bottom line: don't post stuff to ICB that you don't want the world to see.
My apologies if you were offended by the spam, and I'm still not 100% convinced that it falls into the "spam" category. "Shilling", yes sure, but that's a greyer area. I think a two-strikes model works best -- a second post advertising the same thing means deletion and banning.
Besides which, I don't think we've had so much of a spam problem that we even need such a formal editorial policy.
