I think I don't understand your proposal.

You want high rationality people to be rude to irrational or trollish newcomers? Given that the function of the newcomer-behavior is probably attention, I'm not sure we should positively reinforce the behavior if we don't want it.

And I don't see how we can cause high-rationality people to be low status, or why we would want to? (It isn't like newcomers have much idea who is high status or low status).
