This is Kawaguchi Hidetoshi. This is a humble answer to the question.
There is something really painful when you see that the accounts of those who died on Facebook remain as they are...
When it comes to remembering people who passed away, I can understand leaving an account...
There are things that are painful like birthday notifications...
If possible, it seems that it is possible to prevent notifications from coming by making it a memorial account. Remembrance settings are also explained in the Facebook help center. It seems that if you let Facebook know that a user has passed away, they will get a memorial account.
As for the memorial account, if you can afford it, please remember your friends first, join hands, and cherish the day you wanted to live today, and I hope you can adjust your feelings a little bit.
You can't overdo it. It's not a robot. People with emotions can sometimes be unable to smile. It doesn't matter if you don't be rude.
I would like to extend my condolences to my late friend.
