Maybe play another game that isn't pvp centric. Sounds like you have issues with people killing you.
My experience with Mythic CRS is that they take awhile to respond but when they do, they take care of things. They do ban people who are caught intentionally exploiting the game.
If you know this person is going to spawn in this particular spot - get some folks together to be ready for her, or just go elsewhere if you'd rather not die to a better player.
When I say "Red light" stop, when I say "Green light" go.
