How do I report a deceased person or an account that needs to be memorialized?
Memorializing the account:
It is our policy to memorialize the account of a deceased person.
In order to protect the privacy of the deceased person,
we cannot provide login information for the account. However, once it has been memorialized, we take measures to secure the account.
