Hi Pedro
If I understand the proposition correctly, the idea would be to construct a "Death or Glory" sink hole, where "hot posts" consisting of flaming etc would be banished, with posters allowed to carry on 'sparring' with no holds barred, unmoderated, visible only to board members with probably a certain amount of posts to their credit?
It is an idea which suits the conspiracy theorists, who will, for instance, argue till the cows come home, that 9/11 was a government conspiracy, or that Israeli camera crews knew of the impending attack, or that guided missiles hit the Pentagon, not a plane, or that one of the smaller WTC buildings was deliberately blown up etc
ad inifinitum
Please let me tell you why I would not support this: it is more applicable to political message boards, where the concept of 'free speech'(sic)is regarded as sacrosanct, so posts should never be invised etc on pain of virtual death.
But! This is not a political message board. So, nicely, all your proposal would do is to make posters less disciplined, on the basis they would could carry on in a spirited fashion and then, if their thread was sent to the sin bin, unmoderated, well so what, just carry on in the same fashion......and ofc, when they reemerge from said sin bin, they are even more confident, falsely opinionated, and difficult to handle. And so threads become more and more undisciplined as posters care less and less about the consequences of writing poor posts.
This way lies anarchy.
Moving on.....
