There is that, what I found interesting was the first sentence:

From what I can see the initial suspension was due to suspicion that you may have been using a third party program
to control your characters, <NOT OK>
not for the multi-boxing itself. <OK>
As far as I can see the GM has zero problem with multiboxing software, as long as it is not the software contolling the characters (instead of the player controlling the characters).
