What is defamatory?

A defamatory statement is one that would cause an ordinary person to think less of the person the statement is about.
You must consider the imputation conveyed by your posts, as that is what determines whether it is defamatory. Many statements can have a defamatory meaning beyond the exact words used.
Most commonly, a post will be defamatory because of what it implies or infers. The defamatory meaning is often insinuated and can often be read between the lines. This is more easily done when a post is derogatory.
Allegations and rumours — The report or repetition of an allegation or rumour may be defamatory. By posting the allegation or rumour you may give it credence and may imply that it is true. This may be so even if you simply state that you are only repeating the allegation or rumour.
