Facebook has introduced a blue cartoon Zuckersaurus-Rex, or some other type of dinosaur, to warn users when they are about to post something publicly.
Facebook has always had an interesting relationship with its users and their privacy.
Now, users who haven't adjusted their privacy settings will see the dino-message whenever they attempt to share a status update, link or photo that would otherwise be visible to everyone.
Accidentally sharing a public post on Facebook is all too easy. If a user changes the audience of a post on a one-time basis, i.e. to share an update publicly, for example, then all future posts will be made public until the privacy settings are changed again.
Now, under such circumstances, a popup message will be displayed, saying:
Sorry to interrupt. You haven't changed who can see your posts lately, so we just wanted to make sure you're sharing this post with the right audience. (Your current setting is Public, though you can change this whenever you post.)
The message then asks for confirmation of whom the user would like to share the post with - friends only, or everyone.
This privacy check is a welcome addition that should help users manage their settings, as well as generate some positive PR for the company, as it has also been endorsed by privacy advocates, including the International Association of Privacy Professionals, which tweeted:
Are we the only ones who get pumped about seeing Facebook's privacy dinosaur in action?
Whether the dinosaur message is here to stay is not known at this time though - the company says the new feature is nothing more than an experiment.
A spokesperson for Facebook said:
We frequently test new ways to help ensure people are sharing with who they want to on Facebook.
Whatever happens with the dinosaur message, checking your privacy settings remains vitally important and is something that everyone should do, as evidenced by recent stories, such as the girl who lost her father an $80,000 settlement after bragging of the win on Facebook.
Even those on the wrong side of the law could benefit from knowing who they are sharing updates with, as in the cases of Marcin Zendarski who posted pictures of the cannabis he had grown in his prison cell, and alleged burglar Rolando Lozano who discovered that even the police know how to use social media.
How to check your Facebook privacy settings
