The ideas that the staff has made here and in Announcements for going forward addresses what needs to be addressed without sacrificing what does not need to be. I do think that perhaps the staff was more reactive to the trends in Spam because they were forced to see the board because of their permissions; the way in which it was taken down did lead to some confusion though, but had it not been done that way, there may have been an angrier debate following the board's departure.
You make it sound though like posting spam in other places is inevitable, but even so, the rules of those boards have been made clear and people should be aware enough of their behavior to control themselves. Creating a separate forum for spam will also not work in that it is away from ZFGC, you would have to register, and going between forums would be too much of a hassle. It is not that practical.
