We apologize for the problem of receiving requests from neighbors. This has happened because of the new game version we released yesterday. Facebook will soon change it's interface so they want every developer on Facebook to upgrade their apps/ products to the latest version they'll promote in the near future. Since the new version haven't been released to everyone on Facebook, the problem with requests occured without our intention.
We are glad to announce that it's fixed now! Feel free to send / receive requests from your friends!
