Many players may ask a question: How can I remove a neighbor? I wanna delete some unwanted neighbors who are still on my neighbors list who I have removed from my friends list. There is still no way to remove neighbors from our list, and zynga needs to get on this. We are still waiting for the feature to remove pending and hibernating neighbors, here is a reply from zynga support on this question:
Thanks for contacting Zynga.
We are glad to let you know that we are currently working on new neighbor features including: removing neighbors, reminding pending neighbors and removing pending neighbor requests.
Thank you for your patience during our Beta period.
