(CNNMONEY.COM) Facebook has enacted a murky, case-by-case policy on violent content, setting the company on a precarious path.

Facebook (FBFortune 500)temporarily banned graphic, violent content from its site back in May, when clips including a particular video of a woman being beheaded were spreading across the site. That video resurfaced recently after Facebook quietly lifted the ban on graphic videos, and it once again caused a stir.

Facebook defended its decision on Monday after a BBC article publicized the lifting of the ban, but just 24 hours later, Facebook once again decided to take the video down.
