My friends are getting games requests from me which I have not sent. I play Candy Crush and Soda

I keep getting an annoyed facebook friend saying she keeps getting game requests from me.  I don't want to stop playing the games.  Another friend suggested this person takes off her notifications.  Is there anything else she can do because she is blaming me for getting game requests which I have not sent.  I do play the game sometimes but am concerned that friends are getting bombarded by games requests.
