Rule 8: Respect Other People’s Privacy
I usually don’t sign out when I enter my mail and Friendster account. When I first went to a computer shop (this happened around 3 years ago), I checked and updated my Friendster account. I didn’t sign out from my account because that was what I was used to. Unfortunately for me, the next user was a prankster. I just realized it when I found things in my profile that I know I didn’t write. Good thing that person didn’t change my password so I was still able to rescue my account. After that incident, I made sure that I sign out from every site I enter, even if I’m just at home.
