When was this? The one I used to see in All got new moderation (the mod being discussed) who introduced, what I thought, were reasonable rules to encourage actual discourse.
I get what you're saying about it before but, assuming they're being fairly enforced, I assume it's got to be better there now.
They're not supposed to. Passenger traffic on Amtrak should be getting priority but the rail lines basically say "fuck it" and do what they want.
