Because you should play as you would play a board game with friends. When I play cards and someone cannot follow the game because they're busy with their kids, then I just play without them. I don't kick them out of the room and shut the door.
If you're playing a game with friends, and one of them insists on being there, but never says a word, never takes his turn, and just sits there, staring at everyone blankly...are you really saying you'd be just fine with him staying there?
This isn't people who are busy with their kids. That would be someone who autopauses after 2 weeks. This is someone who refuses to give up the IC benefits of being in Perdan, but also refuses to take on any of the IC responsibility.
And, again: you have no way to know how often they're actually logging in. They could be logging in once every 2 weeks to avoid autopause. Or they could be logging in 4 times a turn, checking various strategic bits of info, and feeding it to the realm's enemies.
Or they could be logging in 4 times a turn sending loads of private messages back and forth to their co-conspirators, planning a rebellion. They are, after all, hoarding gold in the capital while everyone else goes off to war.
The point is, they're not following orders, and that's why they were banned.
