Posting pictures of yourself

I really love this app, and want to engage more and connect with other females with same interests, likes, situations. I have a phobia of posting pictures of myself, I see everyone post cute selfies, pics of their family, babies, etc. what if someone screen shots your picture? And now some random person has your picture and can use it for weird reasons, like fake profiles etc. I don't know I always think about stuff like this 😩
