I wouldn't sweat it. I'm sure there are GM's that don't like MB'ing just like there are players that don't like it. It's not up to them to make policy, just enforce it. I'm not sure if you tried reporting yourself, but I do that about once a week to cover my bases with the new GM's (I'm sure there is some turnover in that job). I explain to them what i'm doing, that I own all the accounts and I'm not automating. I also add that they don't need to respond. In most cases, my ticket is closed and I get the "you have been chosen to take a survey" screen. Maybe thats overkill, but I've spent an asston of my kids college money on this hobby. 8)

As for the People who QQ, they are the squeaky wheel while the other three wheels run silent. Most people you pass just look and say nothing. The QQ'ers want to do what you're doing, but can't for any number of reasons. You're best bet is to ignore them. If you can't ignore them, try closing your chats. Some people are just unhappy, and get off on grief. Flaming is a way for them to release aggression. There is nothing you can do for that. Feel sorry for them, and/or their parents, and move on.
