If we had no historical examples of similar empires to similar scales at similar speeds then yes the reaction by the forum will be that it is basically ASB. This depends how detailed the timeline is of course, a well written timeline can justify many things that by summary would be called ASB. But assuming you just posted AHC: Tiny tribe conquers half the Old World in 80 years. then you'd get a lot of not possible.
Indeed, how often do people use the term ASB in any timeline (outside of those on the ASB forum of course?), very rarely, a rareness that is correlated with the how in depth the timeline goes.
