Your profile absence could be confusing for friends and family. It is important to acknowledge that you are leaving Facebook.
I will not be available via Facebook from this point on as I am deleting my Facebook account.
I can be contacted at firstname.lastname@example.org
Please delete any data in your Facebook account that involves me. This includes conversations we've had and photos of me that you can part with.
Please respect my privacy and avoid posting anything in future that personally identifies me.
Personalise as you see fit. To ensure that people have the opportunity to see it, consider delaying account deletion for a few days.
