You're speaking in absolutes, rather than in degrees. Fair enough. But if you insist on using absolutes, it is sloppy logic to "infer" intent. Without a dev comment on the actual intent -- it wouldn't technically be an exploit.
That's fair to say. But remember that "exploit" is a very charged word in an MMO. It's usage in these types of games can hardly be separated from "wrong".
*Shrug* I try not to let myself be limited by other people's limitations
(Especially when I didn't capitalize EXPLOIT, misspell 50 adjacent words, say that everybody around you should be banned, and toss in a few dozen exclamation points, which activities I frequently see accompanying more "agitated" uses of the word 'exploit')
Also, it's not *sloppy* to infer intent, it's *necessary* since we have no reliable mind reading devices. And while a developer's claimed intent may be the final word as far as enforcement goes, it is not dispositive in a factual sense.
