Ask HN: Facebook hack

So a few hours ago I looked at my FB on my laptop. At the top of my profile was a message that my account was memorialized. Doing some digging it seems anyone can submit a request to FB to have one of their friend's profiles memorialized. It appears that when that happens whoever is listed as the legacy contact can take control of some things on the person's page. There is no proof required, you simply fill out a quick form with profile and date of death.

Anyone ever heard of this and is there something going on with FB? It seems like there is significant potential for abuse for this without having to prove the person is dead.
