why is it the players responsibility to figure out which game mechanics are intentional and which are not?

Sorry but you must be on a whole new level if you don't consider that as abusing a game feature.
I probably would consider it as abusing a game feature. But that's for dev's to decide so I simply don't know. In Oxy's case it's clear that he didn't know and why should he have known? Where's the line between clever use of mechanics and abuse?
Oxy didn't know and as a player I don't think he should be expected to know. If it's a server issue then refund and inform the players that it's an exploit and ban them next time. If the damage is easily fixed and its not blatant exploits like duplication or god mode then I think it should always be treated like this.
