Keep in mind that the above assumes that they Have this global and this isn't simply their Live global (which not everyone managed to reserve like I have). +1 for contacting a GM, but as an aside...whomever has control of that person's main computer (with the right understanding) likely has the tools needed to take over any of that person's accounts, for any site, etc. I've had to do this twice now for a parent because they got really sick when Covid started (not covid then) and recently covid took them. So my IT knowledge assisted me with doing this as we had lots of legal things to take care of and being able to access their various accounts was necessary. I imagine a similar effort has already taken place for your friend, so it wouldn't be a leap to say that would help in the Ask of the posting in the event that something like Privacy, etc prevent the current Devs from assisting.
Note: For obvious reasons, I'm NOT going to volunteer how to do any of the above.
