I looked through it and it appears not to be. My first impression was similar to yours, but all was normal on the account until the Fyre Festival and she began complaining about the conditions and how she was having problems getting her father's jet in to pick her up. Friends of hers also had private jets come get them. The things you posted were in response to criticism of her wealth and I think at that point she became angry and started going into full snob-mode.

I didn't say that I dislike rich people, I was just saying that a mutual hatred between classes seems to be common in today's America. Her recent Twitter feed puts that on full display.
