A few things. I'm not American (I'm from India) and I think that fact, plus your point about Yelp, gets to the flipside: that American social media giants' standards are actually more relaxed than the media of many countries, especially non-European countries, when it comes to sexuality, political speech, defamation, etc. As far as beheadings, I'm not sure but I'd assume Facebook is not trying to be a 'gore' destination either. It's the same problem, whether it comes to limits on sex or violence, if you allow any type of media you create havens for that type of content and then it changes the contours of your product. It's all subjective of course, and different companies set different limits--Apple's app store is well known to be more restrictive than Google play, Facebook more restrictive than Twitter, etc.
