unless it's related to outright abuse, insinuated nastiness or flagrant contravention of terms (e.g. posting warez etc) then, without knowing enough about it, by experience of forums I am going to suspect the contentious heated debate that caused this was about..... something not very important
on tech forums specifically, but any enthusiast forum generally, the most heated arguments usually can be allocated under the following concepts:
narcissism of small differences
law of triviality
choose any or all
of course I am happy to be wrong, having no sight of the posts involved, but I've seen it again and again. I hope in any case that either the issue isn't so fundamental really, that no one is being hurt or abused and that we all just carry one once the initial spark of indignation goes out. It's real nice here after all!
i'd also reflect badmojos experience, a few edits for tidy up, a few removals of links and an occasional 'lets end the thread' moderations is what i've seen here and all seems ok to me
