Is this normal for girls!???! taking cell pics of guys they don't know?

The other day I went to the mall wearing all new clothes and my new leather jacket. (all my clothes are new due to my house a burning down) I went with my mom (she needed to shop) and she was going on about how I looked to where she was wanting to fake a car breakdown in front of hot girls' houses but anyways we got to the mall and there were several girls checking me out and my mom spotted one or two takeing pictures of me with their cell phones! Is this normal? What would be the point? None of them knew me because Im not from there and people who used to know me don't recognize me because I changed my looks to where no one would (something I call pedestrian camoflage lol). Anyways what is up with that picture thing?
