I feel bad that the OP lost all of his stuff, but it's difficult for me to sympathize for someone losing their plot when they don't use it. Whether or not you have received notifications from SE is a moot point because of the fact that you have spent so much time away from your home for a notification to even be sent out. This tells me it is more important for you to own a plot that it is for you to actually live there. SE does not, and should not share that same level of priority.

What I do oppose though is the loss of personal items. Those should be zipped up and sent directly to the player. This is where I do have a great amount of sympathy for the OP. But I still believe that quitting a game you claim to love so much over something like this is a bit of an overreaction. I would definitely at least sleep on it before making a final decision to drop the sub.
