Correct, and this goes for pre-existing clans only. The only homes considered for removal are one in the exact clan area, at the time the clan already existed.
If you were in a clan, lived in the clan area, and perm. banned, we would consider relocating the property after 60 days.
If live in a clan area, are not banned but offline for 60 days, and admin may consider relocating your home for the sake of the clan.
But for example, if you built a home and were off the server for a year, and a new clan (or old clan) formed up next to you and wanted to use your land- they would be out of luck.
Homes NOT attached to clans are pretty much left forever and ever. PS or no PS, banned or not banned. All structures on Famcraft are considered permanent.
In the rare event a structure is removed, it is not simply deleted. It is usually relocated to a storage area and labeled, so if the player returns we can set his/her home in a new non-clan location.
