How to safeguard your online privacy (bare minimum)
Decided to start this for a non-IT person .. if you are IT person, you can do better
1. Do not put family photo online, delete them now from Facebook, Google+, photo sharing site blah blah
2. Change your facebook setting to most secure possible ... for photo tagging, always require your approval, go through existing tagging and remove all of them
3. Do not use you actual name in facebook, you can rename it anytime e.g. to your Chinese hanyu pinyin, remove all personal info from facebook
4. Do not use the same nick everywhere unless you purposely want to do it
5. Don't talk about your family online especially in a public forum
6. Do not use LinkedIn
7. Always logout from facebook after each visit
IT will never be foolproof but it will help to fight against kaypoh ppl
Ride at your own risk !!!
