Blizzard agrees with you on that these days. Hence cracking down in WoW in particular. It is just best to realize that same policy will probably apply to other Blizz games. What you described sounds fine. Manually switching accounts and controlling them manually is no problem.
MVPs are players who are familiar with policies, support issues, game questions, resources to point players at, etc. They get nothing besides green text.
I am old, have been here a long time, and yes, in a former life I was a teacher. On occasion I DO use the stern glare on the forums but I have no actual mod powers or anything.
