While I must stress that this only my opinion, I doubt that there is always a clear "black and white" set of rules regarding what is moderated, edited, or deleated on virtually any public forum, here or elsewhere. While one may feel that all forums should go untouched, that will probably never happen -- and I for one am happy that they ARE moderated. There are a few other forums (not on PPRuNe) which I belong to where flaming has not just been a way of life, but has actually gone far beyond flaming and any concept of decency. If someone is looking for more information on a "touchy subject" it is often more effective to "back channel" that info -- and if not more efficient, it seems safer from Corporate eyes. Lastly, while we may deplore censorship we have no right expect that these forums go unedited -- unless you are a fully supporting member (financially) which allows this server to operate.
