GM responses to players seem to be very "personalized". I have no idea if it just has to do with what GM you're talking to and what sort of mood they're in or if they look at other factors with how they respond. Whatever the case may be, you definitely see them telling different players totally different things. So, I wouldn't take a copy-paste of what a gm said to one person, or the parroting of posters on here and reddit, as being absolute "SE-policy"

You know, I bet this sort of thing will pale in comparison to what we'd see from the mobile-app if it doesnt cap the number of transactions-per-day or whatever. I promise that someone will reverse engineer that thing into an offline AH bot 5 minutes after it gets released xP
