I don't know if "fairness" is really the issue in a game where 1 person with TSM and bank alts can completely dominate large parts of the AH and cause more problems for more people than 10 druids draining nodes. AH Barons are FAR more widespread (every server has a bunch of them!) than multiboxers - the problem is the way the games economy is set up and the fact that middlemen are able to insert themselves and drive up prices for everyone.
I agree that boxers should seek to have the least negative impact on others that they can, because I'm not a jerk, but again - I don't think it really matters, in comparison to AH barons, if some people farm as a wildly inefficient way to make gold.
Ha, no. They're vague because people are really good at coming up with ways to cheat. Gamers are like children trying to test the limits with with rules lawyering equivalent to "I'm not touching you!" and it wouldn't matter how specific Blizzard gets.
I've boxed for an embarrassingly long time, across multiple games, and with varying degrees of disruption to other players, and I've literally never once been banned for anything remotely related to multiboxing (I *did* get a forced name change and an 8 hour ban for using an auto-generated name that turned out to be an obfuscated slur though, which was funny). To me, that means that the people getting banned, or reaaaaaallly needing clarification of the rules because they're worried about violating them, know damn well they're walking on the edge and are looking for cover.
