PPRuNe is certainly not without censorship .. that is one of the roles of the mods and admins. However, from what I see, in general and in D&G in particular, the level of censorship is VERY muted and restrained except when things start to get a little too far over the top.
Danny et al appear to be accommodating and accepting in this regard .. we are all very fortunate to have this site as a vehicle for discussion ... BUT ... there is a responsibility to be a little bit circumspect at times ... both in regard to normal civility and the potential for litigation at the other end of the Kangaroo Route.
While I have no involvement with D&G other than as an interested bystander, I think it is fair to suggest that the Woomera team collectively exercises extreme restraint at times ... in regard to the unpleasantness of '89 ... something along the lines of occasional posts trying the patience of Saints comes to mind .....
