People who haven't shared their selfie on SW ,is it tempting to post one ?

You don't have to. It took time for me because of things that happened both here and EP. Just post ones you are more comfortable with. Whether old or new if you decide to and don't send users pictures in PM you don't know. I get that a lot. This is an anonymous site, so it's not required for you do show anything you don't want to.
