1. Birthday

 

Your birthday is one part of an important puzzle which also includes your name and address, with which people can more easily access your bank account and personal details.

 

2. Phone number

 

The best case scenario¹ here is acquiring a polite admirer. Worst case scenario? A stalker who calls you incessantly².

 

3. Most of your "friends"

 

Getting rid of the deadwood can make for a healthier interaction with social media.

 

4. Photographs of your child/young family member

 

Previous generations never needed to consider this, but the advent³ of the internet and social media has given this question more importance.

 

5. While we're at it, where your child/young family member goes to school

 

6. Location services

 

Location services is only available on Android or iPhones.

 

7. Your manager

 

This one is a classic. Facebook is a social media platform, and to some degree your interactions ought to be relaxed.

 

But the CEO of your company can access your wall, he/she has access to every single one of your dodgy status updates - and yes that includes the one moaning about work.

 

Yes you can set your preferences to exclude your CEO from certain update, but isn't that more hassle?

 

8. Stop tagging your location

 

People forget the fact that tagging your location at home actually gives away your address.

 

9. When and where you're going for holiday

 

According to financial website This is Money, travelers who are burgled while they are on holiday may not get their insurance claim accepted if they posted their holiday plans on their social media accounts.

 

10. Your relationship status

 

If you want to celebrate the blossoming of a new relationship, don't do it on Facebook.

 

It may not work out, and the consequent "in a relationship" to "single" status change will make you feel worse than you already do.

 

11. Credit card details

 

Never. This is never a good idea.

 

12. Boarding pass pictures

 

Taking a photo of your boarding pass is often a way to brag⁴ about your holiday, but don't be silly! The barcode on your boarding pass is unique to you, and can be used to find the information you gave to the flight company.
