Female players and weird behaviour

Whenever I play RDO on my own I rarely ever have any trouble with any other players, there's a couple of trouble makers but that's about it. However, when I'm playing with my female friend she is constantly getting harassed, followed, kidnapped and shot at, or they attack me and just sort of stare at her. It's getting really tiresome at this point because it happens at least once per play session, if not more. Has anyone else experienced anything like this?
