The perfect place wouldn’t allow them [people bringing their own shit?] anyway.
As in, isolating the system? No perfect isolation is possible; and even if it was, it would limit the amount of information/entropy of the place. In other words the community would get stale and die.
We could pretend moderators are like Maxwell’s demon, able to sift the newbies one by one; if they’re bringing shit, don’t let them in. The amount of energy necessary to do so makes it unfeasible.
Got it - sorry for the confusion then!
And I need to admit that your take of the mod = Maxwell’s demon thing is way more interesting.
