An individual who makes a ridiculous amount of statuses, always writes on everyone's wall, and overall just a news feed hog.

Mostly unnecessary wall posts, usually just for attention. The worst facebook foul's even wall post to people they have no real connection to.

Another component of a facebook foul is liking or commenting on things that the said person has nothing to do with. Wall posts for conversations are also a tell-tale sign of a chronic facebook foul.

Committing a foul against the social unwritten rules of Facebook.com, including immediate responses, message/wall chatting and most importantly, facebook stalking.
