The forum wars seems like an okay concept, but how will it be censored if it's something inappropriate? Those posts at the top of the page could contain explicit material that is.. well, impossible to miss. I just don't think this is a good idea.
I expect and hope it would be dealt with in precisely the same way that the regular forums are, by a report button above both posts (or above them together as a thread) whereby users can report.
It is no different from any thread, any user can post explicit material in the first post of a thread where anyone else can view it. The censorship is done by a pairing of user and moderator (or moderator alone if it is noticed by them first) That is the best possible way these things can be prevented.
If they make these forum war posts bound by the same rules as any other thread on Gaia, including the image and word filters already in place, I'd think that system would work equally as well for these threads.
