He had been operating a Facebook account under a fake name and posted comments which "could potentially harm young people", documents filed to the Queensland Civil and Administrative Tribunal revealed.

On one picture depicting a man captioned "those who want total equality between the sexes are criminals", the teacher commented “men and women are not equal. If you read this article and reject it, I fear for you”.
