I don’t know. Never heard of them moving people for being inactive. Are you sure your friend’s account hasn’t been compromised, and someone else in control of your account moved to another server? That has usually been the reason when someone returns after an absence and finds their account on a server not of their choice.
If your friend’s character is on a map that is already full, he would go into what’s called an “overflow” map until such time as the map opens up and he gets transferred there (with his permission) later.
We do not move players out of their game world to make more space. I agree with Ic here, I worry that if indeed your friend is on an entirely different game world, his game account may have been compromised. Alternately, he may have moved without remembering, since he’s been inactive and might not recall his most recent world correctly. But again, we don’t move people around involuntarily.
