"It's ok to cheat if you don't get caught." That line of thinking seems to extend into MMO's.
In most MMO EULA's I seem to recall a line wherein "the use of third party software" is a punishable offence. This might not be the case anymore (I tend to gloss over EULA's these days) but if it is then there would be a lot of people who commit that crime (ooooh cyber crime, so futuristic). I think we should pop on some definitions though for clarity. Let's define "third party software" as code created by a company or person, unaffiliated to and/or not endorsed by the game publisher/creator, which gives the user an advantage over someone without the same software while playing the game. That's pretty fair isn't it?
I think we'd all agree that someone who has code to give them god-mode would be pretty unfair (happens regularly in GunZ the Duel I might add), and the guy that runs faster on foot than someone flying in a jet plane is probably hacked. Throw in the farmbot plague which is impressively far reaching when you think about it. These are usually very obvious and no one, other than the exploiters themselves I imagine, would really have an issue with the game masters going after these particular players (or robots, whatever).
But what about that program that changes the font for your client so you lag slightly less, or the one that lets you see the specific durability value of items, or the mod that changes your HUD to make it less cluttered than the vanilla version? Do they give you an advantage over someone who doesn't use it? Let's blur the lines further and ask - what about teamspeak? Or that program that lets you monitor the real time auction house prices (like gw2spidy)? What about youtube walkthroughs? They are all technically software.
Ofcourse the game might actually endorse some 3rd party stuff (eg. GW2 put Dulfy -in- the game, so I take that as an endorsement) in which case those should be absolutely fine - but as for the rest? Guess justice isn't so much a solid line and more a wavy faded noodle, around which the "cops" tread lightly and are fearful or are simply too impotent to go uphold their own laws when it becomes difficult or inconvenient to police (mirrored in real life). That leads to the question - if something is not policed, is it still "cheating"? At what point does "being resourceful" cross the line? I guess the answer to that comes down to you.
It's ok, she's not looking anyway.
