Okay, I'm here to ask a serious question and feel free to insult me as much as you'd like but I'd also appreciate an honest answer:
After X minutes of inactivity, you get kicked out to make room for other players to play on the server. That means that you are on an inactive account.
What's the difference between that and the other 39 accounts of 1 single multiboxer? It's still another account on which technically no one is playing on.
