Parsons signed the nomination form of mayoral candidate and friend Mandy Mayhem-Bullock and Vandervis took a photograph of the form and shared it on social media.
Electoral officer Anthony Morton said this was not a breach of the Local Electoral Act.
Vandervis has said Parsons interrupted campaign speeches and pushed over a sign and he told her "if she continued to troll me I would out her publicly, and I kept my promise".
