To be fair, even if autodemolish came back on, only 1-5% of houses were actually auto-demolished so far when the system was up. And that's because it's either people really didn't resub the game, or forgot, or actually had personal issues that they can't come online at all, or actually dead/hospitalized/has terminal illness.
Otherwise, people who own like 1 whole ward have kept their houses since the launch of auto-demolish because all they need to do is just login, walk into the house. reset the 45 days and log out.
Auto-demolish whether it's up or not, doesn't really change anything but only giving people the extra days to put less 1 hour effort to log in all of your characters/accounts to reset the demolish alerts.
At the end of the day, people who own entire ward/multiple houses will not get their houses auto-demolished. They'll just keep it empty and unused, and watch others cross their fingers that house will be gone.
