We had one girl I remember that tried to pull that stunt. I think she came through rush my soph year and was cut by everyone. She was in the same extracurricular activities as me and some other sisters and she
always freaking asked us when the next COB was or if we wanted to go out to dinner with her, or, if you can believe this, she once asked me and another sister if we were ever going to pledge her or if she should just start coming to meetings.
WTF? Fuh-reak. She finally stopped asking when we just started ignoring her.
