is there a "stalking notification" on facebook?

[Jjbones]

my friend recently told me that there was a notification on Facebook that tells you if your being "stalked by another user" (being stalked = looking at a persons Facebook page more frequently than usual). I tested it by checking my friends Facebook page once a day and have had no "stalking notifications" from either end (my friend or me). does it not exist? or am I just not trying hard enough?
