Game requests to NON friends(Facebook)?

[CMMFTW]

So my ex whom I deleted off facebook has sent me a game request for candy crush...how is that possible since we're not friends?????

maybe you were both playing a different facebook game back before he was your ex, and he still has you on his game list, which is separate from the facebook friends list

Stop the game requests from coming.

click the x mark on the notification then click “turn off” to every different game request. They’ll stop.
