Sorry to hear about your suspension. I contacted Blizzard via in game ticket when I started to multibox recently just notifying them that I was multiboxing and the GM responded quickly, stating there was no need to notify them and multiboxing is fully supported, so that made me feel more at ease, although mistakes happen and I guess there could be a time when my account get a temp ban, hopefully not. The GM that responded stated that there are many GM's and other Blizzard employees who multibox and she wished me well, i thought that was pretty cool.
