Why using someone else's pictures?

I really dont get most of the people on similar world. Why but boobs as your profile picture. And even worse why someone else her boobs? I get that someone doesn't want to put a real picture up vuz of private reasons. But don't use someone else her/his picture. It anoys me.

Similar worlds should be a place to share experiences and learn from each other. So I don't really care that you ate cerial this morning. Or that you're the best at bowling.

And if you're really that desperate for attention you should get a tinder profile or something.
