Things to consider before clicking, sharing or posting online and on social media

In brief: A recent and costly WA defamation decision involving a "self-appointed Internet crusader" is a timely reminder to be careful what you click on and what you post online.

What you need to know:

• Irresponsible social media and online activity can have legal and financial consequences.
• Be highly selective of what you choose to share, re-post or retweet.
• Be careful of being dragged into a comment or twitter war with other users as the posts may start off innocently but can become defamatory.
• A single seemingly innocent tweet may be considered defamatory.
• What you may think is a joke, may ultimately be found to be defamatory.
• Social media should not be used as an avenue to vent anger, frustration or personal grievances.
