Knicker Sniffer 

Someone who snoops around in your Facebook account with the sole purpose of secret snooping. They never like any of your posts or rarely communicate with you. They snoop for gossip purposes.

I have been informed that someone who I have befriended on Facebook and who never communicates through my Facebook is commenting to others about entries on my Facebook account. They are just Knicker sniffers.
