The shower photos would constitute as revenge porn as she has publically denounced them on social media stating that the photographer promised her that they would be kept private and for personal use but later placed on stock photo sites as well as leaked on a single Tumblr.
As for the censored photos, there's a high probability that they are merely suggestive implied nudity, covered, or even clothed "lewd night posting" she did during that year. The simplest explanation would be that this individual managed to save them before they were deleted. Another hypothesis could be that the more suggestive photos were posted anonymously on any of the myriad of Tumblrs that cater to erotic anonymous user submissions and someone stumbled upon them and managed to put two and two together.
Now that more than half a decade has passed coupled with the Tumblr acquisition and sexual content purge, it's highly doubtful many people if any have those images saved and for those that did an even lower probability that they are motivated enough or even aware of places like this. Potentially they may still exist on an abandoned blog that was never purged or closed that reblogged those images but if it was difficult to find anything then it'll be almost impossible now barring access to commercial-level searching.
The Discord claim is often repeated and a misunderstanding as to who the seller was as she never sold anything on her Discord or Snapchat and if she did then there would be a lot fewer people whining. As for the more outlandish unsubstantiated rumours pulled out of thin air, those can be attributed to those individuals' fetishes and completely fabricated.
