I would agree that it should be unacceptable considering the limitations of the ward system that SE has chosen to use.
Clearly SE disagrees with both of us since they do allow it. We need to stop finger pointing at the players doing what SE allows.
It's on SE's shoulders to make changes to the system and either disallow house ownership beyond the one personal/one FC per service account, or to add enough wards that all players who want to own a house can do not only that but also own multiple houses if they desire without what one player having impacting what another player can have.
Using a fully instanced housing system would have made that very easy to achieve and probably would have been far less expensive than the ward system they picked. Oh well.
