There are many thing to beware of, because nowadays there are many social network. Even if you are very careful when you post your photos online or write anything too personal online, you still need to beware of virtual world.
I am sure all of us have friends, and our friends also have online social network. Even if you don't post it online, your friend may do it for you , without your consent. Everyone have their own rights to take photos, and everyone have their own rights to post their own photos online. Unknowingly, the photos not only contain the camera owner's face, but also owner's friend face.
Recently I joined swimming class with my friend. My friend is an extreme camwhore. Always carrying camera around (asking people) to take photo of herself.
As usual, with her camera, we took a photo with our coach, wearing our swimming suit. Not long after that, she uploaded it to online social networks.
LUCKILY!!! When I took the photo, I covered myself modestly with a towel. IF NOT, I don't know how to face the world!
As Danny said, Less Cloth not necessary SEXY!
The photo actually is nice, it is suitable posted online because I look modest with the towel. Luckily I didn't listen to her advise to remove the towel and let all see my ........ ahhh malunya (shy).
So beware when taking photos with your friends! And also beware of my camera! Snap snap snap!
