The people who sperg about the lack of death certificate and obituary just don't know how these things work. Whether or not an obituary is published is the family's decision, and Ciara's family not only knew of Keeruh's "stalkers" and online notoriety, they also knew that she had specifically overdosed, which, for a family, is very shameful whether they say it or not. I'm sure they feel like failures and don't want that information to be public, especially since people could and would deface any obituary with troll comments. And in order to obtain a death certificate, you have to give out your ID and have information on the deceased person along with proof that you had a real IRL relationship with them.
