Not sure I understand that one??
Why do members read a post of a disgruntled new OP - I think it is for one of (or both of ) two reasons: to attempt to understand and assist the poster with advice, or to learn from the OP's experience. For both of these, it is necessary to understand exactly what happened.
I know that a newbie OP will not immediately think of all the info that is needed - everything from class of travel to airline, etc etc etc. And this will need questions to be asked. Likewise, when there is a major element of the OP's story that simply doesn't make sense, then it is natural that people reading the thread will want to know more, to try to understand it.
In your above post you refer to a newcomer "unknowingly breaching" a "designated 'rule' or 'standard'". That is not relevant or accurate in many of the newbie rants - the only "rule" or "standard" that they breach is the truth!
In that dang Virgin thread, the OP made the extraordinary claim that Virgin had (1) admitted they overcharged him, and (2) told him to get stuffed anyway. He submitted an email from Virgin to support this amazing claim. But he redacted the part that actually said completely the contrary. Hello? That is not some inadvertent breach of AFF customs - it is an untruth (or lie, or fib, or whatever else). You and many others chastised the few members who stood up and questioned the OP's "story".
So although some speak of new members possibly being scared off by a "hostile" reception (that being the demand for truth), it seems it is ok by you and so many others to be hostile to established members who just want the site kept slightly honest, and not just a place for anyone to vent whatever story they have in their head, unquestioned?
