Only if they politick like humans do. Perhaps elves don’t think politics makes any sort of sense and instead defer to ancient kingships á la Tolkien. No elf is creating intrigue around Galadriel or Elrond, they are just as they are, and are revered for their ancient wisdom.
Or perhaps the idea of hierarchy itself is completely alien to them. After a few thousand years a lot of the trappings of mortal power may just not be of any interest anymore, and every elf is a sovereign unto themselves.
Frankly? This sort of response above is unhinged. If this person is as awful as you say, just get them out of your life and move on. Trying to document everything, calling their friends and family, spending this much time on someone who is awful and not worth the time nor the effort? You’re going to drive yourself crazy and somehow they’re still going to be in your life making you miserable.
I’m sorry this person is terrible to you, but the best “vengeance” is forgetting all about them and being happy doing what you want to do. The more space they take up in your mind, the worse you’re going to feel about the whole situation.
