An old high school friend of mine died a few years back and I am still getting birthday notifications on Facebook. His profile just sits in limbo, a record of his activities the last few weeks before he died.
I think there's some way to notify Facebook of his death so they can "memorialize" his profile. Then, according to his settings, it will either be deleted or converted into a memorial managed by some contact he elected.
I will check this account, thank you!
