Brought this up in another thread...

Instances have a limit to the number of players be that inside the house or out of it..

If enough people are tired of these kingpin mafia style house hoarders you could flood the instance once the demolition time is back up and keep it full.. youd need to stay for over a month without logging out but it would force them to lose their house..

With how many people afk in Limsa and never leave i don't think it would be impossible lol
