Changes have been made in how abandoned land on the main land is handled. I’m not into buying SL land so, I’m not sure exactly how it has been working. However in the Simulator User Group the Lindens were discussing changes to the system. (link)
When tier is not paid land goes into an abandoned status. For three days the land is in a BUY BACK grace status. The owner can buy the land back for L$0 cost. The precise timing is a bit fuzzy. As I understand once the computer systems mark the land abandoned, the counter starts. No one knows exactly when the counter starts, or at least they didn’t say. As best I can tell there is no way for a resident to predict when someone will abandon land, unless the owner tells them. Even then I suspect there is no way to know when the computer will update the land’s status.
