Per the text in the post, it seems that someone was going to attempt to extort money by holding an account ransom. They then realized that the, likely deceased, account owner had a notable history. Rather than disappear the account without a stated reason, causing further confusion over the abandoned account, they opted to inform the followers and remind them of Tiffany's story and the public's unanswered questions.
So is she dead? I'm still confused
To the best of my knowledge, that has not yet been revealed.
Seems like the twitterer revealed answer
Her name showed up in an official dead people database, dont remember the name, and she has been replaced by a phony. When she's still disappeared it's quite obvious that she's dead
