According to the blog, X (formerly Twitter), Pinterest, LinkedIn, and other platforms can also access users' data in the same way, through users liking and sharing of content.
Your birthday, together with your name and address, could be the key for criminals to get their hands on your bank details and other personal data.
While it's understandable that you'll want to share pictures of your family and friends who live far away, take care.
Don't share the location of where you publish photos, videos and statuses. Be especially careful about keeping your home address secret. Facebook could use that information without you realizing, by getting it from old posts.
This is a question of common sense. Facebook is a social network on which users can communicate freely and share photos, videos and any thoughts, rants or complaints. But make sure this doesn't backfire on you - if you want to express anger at something or someone, it's probably best not to spread it all over the internet.
It might seem obvious but make sure you don't let your bank details fall into the wrong hands, and be extremely careful with how you share them online, even through private messages!
