Fan who takes Polaroids Pictures at Stage Door on Broadway

I don't know if anyone else has talked about or seen this person around Broadway. But I regularly attend Broadway shows and there is this one intense fan girl who shoves a polaroid camera in the face of the actors at the stage door I've seen at 3 different Broadway stage doors in the last few weeks. Seems to make the actors genuinely uncomfortable, and holds up the line of people waiting to have their Playbills signed. I don't know why security doesn't regulate the stage door better, surely they must be familiar with these very intense fans.
