There seems to be a misconception that PPRuNe is somehow supposed to be democratic and about free speech.
It isn't.
It is the creation of one person, who now has a lot more people helping him. He gets to make the rules (and graciously does so in consultation with other moderators), and the rules are the rules (and not open to interpretation).
I don't always agree with the rules, but I absolutely agree with the right of the boss to make and enforce them. All who use this board should respect his wishes.
If you want to keep on endlessly dredging up past (alleged) injustices and (alleged) unfairness, why not start your own BBS where you can argue about it until the cows come home (although even cows would no doubt be sent to sleep by it all). It would never have many members, but it would spare the rest of us the bickering.
It was a bad time, but individuals made their beds, etc. As the Americans say- "get over it" or "get past it".
